INTEL PENTIUM D 930 PRESLER REVIEW OVERCLOCKING POWER REQUIREMENT By :cpu review Posted:2006-07-23 xtreview is your : Video card - cpu - memory - Hard drive - power supply unit source Processors Intel Pentium D 9xx appeared in sale so long ago, we had the low-end processors- Intel Pentium D 930 to test However, at  the moment those processor appeared in  large party oem- in local shop, the overclocking result has been improved with stepping update. we had picked four processors - one Box and three oem.. On the reverse side of the processor packing   the cooler can be seen. This is the most usual aluminum cooler with the copper base. in the upper part of the packing we can see the  processor, By the way, the processor was a SL94R and here is the   characteristics . Box and oem- processors was  completely identical, . They are based on core Presler of stepping B1, their regular vcore of 1.288 v, according to the data RM Clock Utility 2.1. Furthermore, processor was assembled in Costa Rica, and oem- processors in Malaysia. processors testing was in open case with the following configuration: motherboard- Asus P5LD2 Deluxe, rev. 1.02, bios 0506; Videocard- Chaintech GeForce 7900 gtx (24p/8v, 650/1600 MHz); Memory - Corsair Twin2x1024-8000ul; Hard disk - Western Digital Raptor WD740GD; Thermal-paste - from  Zalman; Cooling system - Tuniq Tower 120, 2000 rpm; Power unit - Sunbeamtech Nuuo Sunnu550-euap (550W); Operating system - WinXP SP2. The memory  working  frequency would not prevent the processors overclocking. The absence of troteling was checked using utility RM Clock Utility 2.1 . The preliminary check of the operational processors stability  passed with the calculation of 4-8  mb. by using  Super Pi utility  . we the first processor we was able get only 250 MHz FSB . Not far from it the second oem- processors, was passed test at the frequency of  255 MHz fsb. Then the results, shown by two left processors, proved to be noticeably better and was close to: 270 and 275 MHz. the best  processors Intel Pentium D 930 actually was capable to stably  operate at  frequency of 275 MHz, when we checked using the utility S&.M,  which was propose to very strong loads in the processor. the  total final result gotten was - 265 MHz with default vcore, Almost 4 GHz with the default vcore - this is a good result for dual processor, processor Intel Pentium D 930 on 65 nm core Presler is very favorably related to vcore. To each increase in Vcore it corresponded by an increase in the frequency of stable work. As a result  processor was capable of  the frequency of 290 MHz with vcore 1.45 v. This is was good result, especially for the dual core processor, this is not "screen shot of death", processor Intel Pentium D was  capable to do  all work under these conditions,. You know when a dual core processor work at the frequency of 4.43 GHz with vcore 1.5 v, this would result in ton of heat even mouse and keyboard will heat :-) no I am just kidding .but surrely mofest and transistor and all motherboard component was simply stressed the cpu fan was working aat the maximun speed, and noise start coming from the power supplay to prove the high power requrement issue With the use of instrument called Extech Power Analyzer 380803, we measured the energy consumption of system coupled with D 930 with different frequencies and under  100% stresses  - from S&.M. Results are showin in this table. FSB 200 265 275 280 285 290 295 V 1.288 1.288 1.3375 1.375 1.4 1.45 1.5 W 225 250 270 284 293 315 338 The graph show the dependence of power consumption in order of vcore and frequency increase. The energy consumption of system it is dependent also on the temperature. During the day, when the measurements of power were calculated, room temperature was comfortable and the required power was lower by  4-7 W . Furthermore, much it is dependent on the composition of system. The replacement of the generic default air cooler by a water cooling system   added immediately 20 W! Difference arose because of the addition of pump and two slow fans 80 mm Is now understandable, why the overclocking of processor Intel Pentium D 930 to 4.43 GHz reached is completely real, it cost  338 W - this very much, during the tests of AMD Athlon 64 3800+  to 2.85 GHz  it did not go over 200 W, Thus, our checking showed, that processors Intel Pentium D 930 can be very well overclocked. For the successful overclocking it is required to get a powerful power unit, motherboard, capable to handle such stress and by  highly effective processor cooling system  asembling those 3 factor u can get such results, but in our statistics of the overclocking  of  such processors alwais lack for 1 or more those factor . If dual core  processor  is already necessary, maybe u should look first in the AMD Athlon 64 x2 or Intel Core 2 duo processor first .the price will play big role for witch processor u should pick up 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
