E6300 REVIEW INTEL CORE 2 DUO BENCHMARK OVERCLOCK TEST By :cpu review Posted:2006-09-03 xtreview is your : Video card - cpu - memory - Hard drive - power supply unit source today it becaume easy to overclock the cpu: it is not necessary to collect complex combinations on DIP- switches, or to clear the CMOS, since the new motherboards   has already the auto restorefunction witch get your system working back  if bios setting fail or /and wrong . u simplt need to decrease the memory frequency  and then increase the bus frequency , add  a little  vcore on the processor, if this is  necessary to get the cpu working stably at high speed . when u are done with your cpu u can now go in the memory overclock frequency and timing and then time for video card . well during this test we used two motherboard , two cooling unit and two memory module from variant manuficulture.and as alwais a set of programs  and utilities.Of course we tested not all theoretically possible combinations, but majority of them. . I tried to describe everything in detail. Therefore in this article I will briefly present the checking motion , focusing attention only to the basic moments. For the tests we received five processors Intel Core 2 duo E6300 (1.86 gHz). They all was assembled in Malaysia and they were marked SL9SA. At the given moment these are low-end processors ; therefore they are especially interesting to overclockers and  for the overclocking result it should not varie a lot since those cpu require high fsb and motherboards will max out before the cpus . For  convenience the processors was numbered from one to five. The first pair related to one party, which were left three to another, but their characteristics was identical. Without knowing, which of the motherboards is better to overclock those processors, I solved it to began with Asus P5W DH Deluxe.   this board, in my view, is very interesting. DH indicates Digital Home: the motherboard is completed with the panel for remote control, by module WiFi, technology ASUS EZ-Backup allows to work in RAID- massifs without  using  drivers or preliminary bios configuration  . For the present here is the list of the basic overclocking  capability of  Asus P5W DH Deluxe: Frequency FSB: 100-500 MHz with  step of 1 MHz; Memory DDR2 400/533/600/667/800; memory voltage: 1.8-2.4 v with  step of 0.05 v; processor voltage: 1.225-1.7 v with  step of 0.0125 v; Chipset north bridge voltage : 1.55-1.85 v with  step of 0.1 v. Attention! The early versions of Asus P5W DH Deluxe motherboard  allowed to increase voltage on you chipset  to 1.65 v only, what it is clearly insufficient for   successful overclocking. Unfortunately, there is no reliable method to  determe the correct motherboard , but the later it is released, the greater chance to get a good one with 1.85v . Initially on the motherboard was installed the bios  version 0801, and it  functioned correctly with it, but soon we updated it to version 1101 the freshest at the moment. With the update we encountered difficulties - utility EZ-Flash2 rejected to switch back to the old version,  it was necessary to use FDD.in the new bios we can save up to two profile     . it is also Possible  preserve two memory profiles, two sets of  parameters  the board  load them if necessary, The composition of the system test , on which were checked the processors, appeared as follows: Motherboard- Asus P5W DH Deluxe (Intel 975X), rev y..02G; Memory - Corsair Twin2x1024-8000ul; Video card - Chaintech GeForce 7900 gtx (24p/8v, 650/1600 MHz); Hard disk - Western Digital Raptor WD740GD; Cooling system - Corsair Nautilus500; Thermal-paste - Zalman; Power unit - Sunbeamtech Nuuo Sunnu550-euap (550W); Operating system - WinXP SP2. at the  frequency FSB of 440 MHz the system started and passed preliminary tests without any voltage increase . So to go with higher frequencies, it was required to increase  the voltage on the chipset north bridge. The best result, was shown by the first processor, was equal to 475 MHz "system bus". In this case the vcore was slightly increased to 1.35 v, on the chipset raised to 1.85 v, and on the memory to 2.0 V. stability was checked by the utility Super Pi simultaneously with BurnK7. not bad  result for this board ,and how now for the Asus P5B Deluxe/WiFi- AP? photo from the  producer site This board also look good. For those interesting about the detailed description here is the link on site Asus Asus P5B Deluxe/WiFi- AP . the board was obtained with the early bios version 0204, she worked with processors Core 2 duo, but with each start issued error "Intel CPU Code Loading error". the bios  was updated to the freshest version 0507, on this motherboard it is look like the bios is stored in the chipset Here is the brief enumeration of the Asus P5B  possibilities , Rev 1.03 G: Frequency FSB: 100-650 MHz with  step of 1 MHz; Memory DDR2 533/667/800; memory voltage: 1.8-2.45 v with a step of 0.05 v; processor voltage: 1.1-1.7 v with a step of 0.0125 v; north bridge volatge: 1.25, 1.45, 1.55 or 1.65 v. the board cannot open the auto- video card overclocking , there is no parameter PEG Root Control. Possibility to establish 650 MHz FSB was  a dream, but   without  use of any special methods this will not succeed.  in comparison with Asus P5W DH Deluxe the board showed lower   possibility chipsete voltage, and the poorest memory operatiion mode On the board Asus P5W DH Deluxe we can  get the  memory as DDR2 400, but with the fsb at 475 MHz . In the case of  the motherboard Asus P5B Deluxe the situation is   more complex.   we can get the   memory as DDR2 400 only in interval of FSB from 100- to 147 MHz. It is natural that no one will use such frequencies  with processors Core 2 Duo. In all remaining cases the minimum memory frequency   is 533 MHz, which with the fsb to 475 MHz  requires  the memory to  work at the frequency of 950 MHz! So   we can  load the operating system on  Asus P5B Deluxe with FSB frequency  of 370 MHz with  chipset volatge at 1.45 v .the board would pass the tests on  frequency of 420 MHz at 1.55 v, and final result proved to be approximately the same as on the  Asus P5W DH Deluxe. Processor earned  the frequency of 475 MHz with a vcore  increase  to 1.35 v, chipset volatge at 1.55 v,  memory volatge at 2.2 V. stability was checked with the simultaneous utilities BurnP6, BurnK7 and  Super Pi 8M. So what board overclock better , if results are identical? Either in the processor  limit us, or board are limited to 475 fsb ? The mothebroard Asus do not explicitly indicate the nominal processor vcore .  Asus P5W DH Deluxe showed  1.3-1.32 v, while  Asus P5B Deluxe - exactly 1.288 v. obtained value of 1.325 v was confirmed by utility RightMark CPU Clock Utility, which, beginning from version 2.15,worked correctly  with Core 2 duo. Thus, all processors was checked on both motherboards with the regular vcore of 1.325 v. on  Asus P5W DH Deluxe  chipsete voltage  was set to 1.75 or 1.85 v, depending on processor, 2.0 v on the memory . on  Asus P5B Deluxe chipsete voltage was set to 1.55 v,  2.2 v. on memory   CPU 1 2 3 4 5 Asus P5W DH Deluxe 470 450 460 475 475 Asus P5B Deluxe 465 445 460 475 475 It is obvious that we have two leaders - fourth and fifth processors, the third is   weaker, and the second is located on the last place. these are preliminary results, since the tests passed with the nominal vcore was only  using  utility Super Pi. It is also evident that the overclocking  results  are approximately identical on the different motherboard; however, they  are slightly  better on Asus P5W DH Deluxe. On this board was continued more detailed checking, so we used more effective cooling such Tuniq Tower 120 - instead of the expected improvement a drop in the overclocking  results   occurred. I assumed that the chipset was overheating  . Tuniq Tower 120 creates powerful airflow, which blows out air  on transistors, but chipset radiator   heated a lot  - with the increase in the chipset volatge and   intensive processor work   during  tests.  I installed two slow fans 80 mm, which directly cooled both radiators and memory at the same time. Subjectively during this cooling the chipset temperature was lower. By the way, we reverse attention, that Asus company   after a number of tmotherboard, where all transistors MOSFET were equipped with radiators, again did return to the halved solutions?  Asus P5W DH Deluxe and Asus P5B Deluxe have  eight-phase diagram to power the processor, but radiator is cooled only half of transistors. and this is the defect of those board . Transistors are don\'t  heat a lot , they can  worked  without  additional cooling,, but radiator in essence was intended for  heat dispersion from the chipset north bridge  . To the northern bridge was established Cooler Master Blue Ice Pro. photo from the site of the producer the chipset temperature after the  installation  of Blue Ice Prowas was reduced.   Unfortunately, even after the replacement of chipset cooler  the work stability did not improve. Problem concluded even without using stability software,. Utility S&.M, which we constantly used lately, was developed before the appearance of processors Core 2 duo, she put outs error in the  first test " cache test " even at the defaultfrequencies. Utility Prime95 also  rapidly show error .  even  program OCCT,crash directly According to my observations  the greatest  heat for  processor Core 2 duo is  obtained with the aid of the ancient utility BurnK7. According to the data the maximum energy consumption was obtained with the use of the analogous utility BurnP6. . Utility Super Pi test the processor and memory,. Therefore I used complex test "3 into 1": Super Pi, BurnK7 and BurnP6, . Finally I started testing the ram ,and found that the error will show up  instantly. The presence of errors was confirmed  by utility MemTest 86+. Natural suspicions about defect module arose, but replacement with  Patriot PDC21G8000ELK give nothing, just the same. During further tests on  Asus P5B Deluxe with different conditions was discovered interesting special feature - if we set the memory  timing to  regime Auto, then the memory  tests   would pass.we can not  achieve the maximum overclocking in this regime since  the system don\'t boot up  with default timing and memory frequency at 400 mhz o, but she worked with FSB 380 MHz. However, the  Asus P5B Deluxe put out timing 5-4-4-10, 4 it used even more relaxed  5-5-5-15, but  utilities, which test the memory, immediately issued error. Attempt to set  timing to  5-4-4-10 bring nothing, Further tests showed, that  the best way to checks stability is the utility Prime95. So that  would load  immediately two core, I started simultaneously two copies of this utility: one in regime Large FFT, the second in regime Blend - Now, when basic problems was more or less solved, possible to contunie with  the final processors checking . As a whole  results coincided with the preliminary tests (see the Table abrove), but they presented some surprises. As it was expected, best result appeared with fourth and fifth processors. The fifth with use Corsair Nautilus500  passed tests at the frequency of 485 MHz with vcore at  1.425 v, and after transfer to Tuniq Tower 120 and vcore increase  to 1.45 v to we get the frequency of 490 MHz. In  cases for stable work chipsete volatge on  Asus P5B Deluxe was  raised to 1.55 v. The fourth processor passed tests with the default vcore on FSB frequency  of 455 MHz, it managed the frequency of 490 MHz with vcore of 1.425 in, and  here the following stage - the frequency of 495 MHz, witch we could not get . but stability was obtained at the frequency of 493 MHz with vcore of 1.45 v. The first processor  lagged behind the good pair , after getting in  the frequency of 475 MHz with vcore of 1.4 . all is completely regularly, and surprises  was obtained from the second and third processors. The second processor was the weakest according to the preliminary tests results  , and  this was confirmed, since with the default vcore it can passe checking only at the frequency of 430 MHz. But it turned out that with   1.5 v it can  work with Tuniq Tower 120 at the frequency of 475 MHz, that also was confirmed with more than hour of testing using  two simultaneously  copies of Prime95.  the maximum overclocking capability  overtook the first processor, which originally looked better. However, the third processor, which during the preliminary tests appeared better than the second, presented unpleasant surprise. With the default vcore it was able to operate at the frequency of 455 MHz and this is all. It  rejected the vcore increasement, it started at the frequency of 460 MHz, loaded Windows, but it could not  maintain stability with Prime95, and it could not even start at the frequency of 465 MHz! Apparently,  because  such processors went rumors, that series Core 2 duo  are bad clocker. However, in other language the frequency of 3.18 GHz is not bad that all. about  temperature , during the tests   the maximum frequencies  never   exceed \'60c\', being usually located in the region of 56-58 degrees. The   replacement of memory modules Patriot PDC21G8000ELK on Corsair Twin2x1024-8000ul showed no improvement the same overclocking result. The replacement of the chipset cooler by  Blue Ice Pro do not help to get higher frequency, although the chipset was lower. The series processors Core 2 duo overclocked rather well, moreover with the   FSB from 266 MHz to 430-450 MHz   do not require increased  Vcore. For the successful overclocking u need high fsb capable motherboard, and high-speed memory frequency. your board must allow the chipset volatge increasement and this is all At the given moment there are no tests, capable rapidly and reliably to confirm the stability of processors Core 2 duo. I would  recommended the programs BurnK7 and BurnP6, which will provide the maximum heat  for your processors. For the preliminary check Super Pi,  checks processor and memory, but it does not give complete confidence in the operational stability. Prime95 is sufficiently effective, but it is inconvenient  that it requires very long testing from 12 to 24 hours. xtreview is your : Video card - cpu - memory - Hard drive - power supply unit source we would be happy to answer for your question . if you have suggestion or comment regarding this review our support would be glad to help just join our forum and ask u will get the best answer to discuss check our forum section :-) RATE THIS REVIEW 1 2 3 4 5    / 5   View Stat
