PENTIUM D 805 AND CELERON D 356 - REVIEW - OVERCLOCKING BUDGET INTEL P4 CELERON By :harwdare review Posted:2006-04-28 xtreview is your : Video card - cpu - memory - Hard drive - power supply unit source Pentium D 805 and Celeron D 356 - review - Overclocking  Budget Intel p4 celeron   While everybody is waiting for Intel to release the next big thing, Conroe, the release of two new processors almost caught the enthusiast and media off-guard. The Pentium D 805 and Celeron D 356 are priced lower than the competition so are they interesting for the budget friendly overclockers out there? Let´s take a closer look and find out Introduction to pentium d 805 and celceron d 356 While AMD has been getting quite a lot of deserved attention from the enthusiast crowd it has recently come to our attention that for those looking for the best bang for the buck overclocking system, Intel might have something up their sleeves. With the introduction of the Pentium D 805 Intel is offering a Dual Core CPU at half the price of the cheapest AMD Dual Core offering, and for those looking for even cheaper parts the Celeron D 356 based on 65nm process has been released too, challenging the AMD Sempron product line. While performance of both parts have been compared to the competition numerous times, we thought it would be interesting to see how these two ???budget??? CPU would overclock using plain air cooling (It??в„ўs hard to justify installing a $600 subzero cooling on a $150 CPU) Specification Comparison  pentium d 805  vs celceron d 356 Celeron D 356 Pentium D 805 Clock Speed 3.33Ghz 2.66Ghz Dual Core no yes Core Name Cedar Mill SmithField Technology 65nm 90nm Features MMX,SSE,SSE2,SSE3,EM64T MMX,SSE,SSE2,SSE3,EM64T L2 Cache 512Kb 1024Kb FSB 533Mhz 533Mhz   The Motherboard We had to find a Socket T/S775 motherboard which offered good overclocking abilities but didn??в„ўt cost an arm and a leg, the Asus P5LD2 based on the Intel 945P chipset priced at ~$110 seems to be a good choice CPU Support: Intel Pentium D/Pentium 4 HT/Celeron D DDR2 Standard: DDR2 667 FSB: 1066/800MHz PCI Express x1: 3 PCI Express x16: 1 The motherboard??в„ўs chipsets are cooled passively interesting for those who like to build a silent budget PC The Asus P5LD2 comes with enough features to not leave you wanting; you get RAID 0/1/5/0+1 support, onboard sound and network. For a more details on the P5LD2 check out the Asus product page. The BIOS on the Asus offers quite a lot of options to get your system running above default You have control over the FSB/Memory divider, so you can run the memory asynchronous from the FSB if you are using lower clocked DDR2 sticks. DDR2 voltage can be increased to 2.3v. CPU voltage goes all the way up to 1.7v! If you are lucky enough to get your hands on an ES (Engineering Sample) you can control the CPU multiplier also in the BIOS. Last BIOS screen shows the variety of memory timings you can adjust. Test Setup for Pentium D 805 and Celeron D 356 Windwithme's Test Setup CPU Cooling Thermaltake Sonic Tower & Stock Cooling Mainboard Asus P5LD2 Memory 2*512MB DDRII 667 Video nVidia 6600GT Other Seagate 7200.7 80GB SATA Maxtor 30GB 5,400rpm Seasonic 380W PSU   Time to start up the system and see how the CPU??в„ўs can be overclocked The Pentium D 805 was cooled with a Thermaltake Sonic Tower equipped with two 120mm fans, the Celeron D 356 ran a lot cooler and stock cooling was enough for our overclocking adventure. That the Pentium D 805 gets hot when overclocked is not news, in combination with only 3-pashed power circuit from the Asus P5LD2 (instead of a better 4-pashed circuit) the backside of the motherboard got so hot that it burned through foam lying underneath: Overclocking the Pentium D 805 Running at stock speeds the 805 only needs ~1.35v vcore to remain stable; At these settings the DDR2 memory is running with ½ divider at 266Mhz CL3-2-2-4 using 1.8v voltage setting the BIOS Increasing the FSB the CPU overclocks easily to 3.3Ghz without touching CPU vcore settings, the DDR2 is still running with ½ divider and gets a bump to 2.1v. At 781Mhz Front Speed Bus the CPU is at 3.9Ghz, a small bump to 1.5v vcore was needed for this, the memory is running on 3/5 divider. The system started to act up once you near the 200Mhz FSB mark (800Mhz quad pumped), at 3.9Ghz it was rock stable, 4Ghz (the limit of the system is seemed) was reached but not 100% stable. It turns out once you disable SATA and hook up a PATA hard drive the system ran successfully at 4.2Ghz Having only an older 5400rpm PATA drive available the 32Mb SuperPi test was lower than expected. Since disabling SATA is not a feasible solution we only compared the benchmark scores of the 805 clocked to maximum 3.9Ghz. Benchmark CPU scaling Pentium D 805 Overclocking Celeron D 356 Overclocking the 65nm Celeron D 356 went quite smooth and with the large multiplier the CPU speed rocketed sky-high until the same FSB wall was reached, the end result is a 1.5Ghz overclock with only 1.4v vcore. 3DMark03 benchmark To make things interesting AMD??в„ўs latest, the FX-60 was added to the comparison, default it runs at 2.6Ghz but overclocked to 3Ghz it was stable when using adequate cooling.   Although the FX-60 beats the D805 easily in the CPU test the overall score is in favor of the D805, which is weird, repeating the test several times didn??в„ўt change the outcome. The Celeron D 356 has a clear Ghz lead but it doesn??в„ўt translate in better performance as it trails the other two configurations. Overall thoughts Pentium D 805 The price of this CPU is extremely low which makes it a winner as a budget CPU, even when not considering overclocking, a Dual Core CPU at this price is the best thing Intel has done up until now this year! They??в„ўve also included a better standard Heatsink/Fan combo which supports auto fan speed adjustment, allowing the Fan to be quite silent when running idle. For the price this D 805 runs almost as fast as the best out there when overclocked. The draws backs are its high power consumption and when overclocking you??в„ўll have to invest in better cooling to keep the temperatures down. The Asus P5LD2 limits the overclocks to ~200FSB, going any higher you loose the SATA ports. Celeron D 356 With its smaller manufacturing process this CPU runs cooler and uses less power, when you step on its tail it overclocks like crazy even with modest air cooling, reaching speeds which could only be had with sub zero cooling one year ago. However its reduced cache size makes it slower than the competition even when running at close to 5Ghz! The new Celeron D will make an excellent competitor for AMD??в„ўs Sempron which has been regarded as the budget-friendly CPU??¦ until now?   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
