4 edits | Undervolting RAM = Prime95 Blend failure? I have these specs:
Asus P5WD2-E Premium
Pentium D Extreme Edition 3.733GHz @ 4.094GHz
OCZ Platinum 4GB (2 x 2GB) DDR2-1066 (OCZ2P10664GK)
BFG NVIDIA GeForce GTX 275 (OCE overclocked to OCX speeds)
Thermaltake Purepower RX CM 500W
I am running my CPU at 292 FSB @ 1.2875v (the mobo adds .05v for some reason according to CPUZ/HWMonitor) so the range is from 1.3375 to 1.22 which is what Intel lists for stock speeds, and the AUTO setting for this board/CPU weighs in about 1.25-1.35.
I'm running my memory at 3:5 which is just a tick below the 1066 setting (actual speed/DDR2-533). I have set my memory to 2.1v which is the manufacturer's recommendation for 1066 but it's at 975MHz. The timings are 5-5-5-12. The reason is that the board might not be able to run the memory at 1168MHz, I have not bothered to try but will run at 1066MHz with voltage adjustments.
Anywho, I decided to try and undervolt my RAM by .1v and it passed Memtest86+ 4.20 with no problems, but when I run Prime95 Blend two workers immediately failed. I had been playing games or whatever before actually running Prime95 and had experienced zero problems. I upped the voltage back to 2.1v and Prime95 ran fine.
Other than the ha-has and he-hes, that my system is super old, anyone have any insight to Prime95 failing outright when the system is otherwise stable when having undervolted the RAM? I played Team Fortress 2 and GTA 4 which are CPU and memory hogs.
MCH - 1.60 (stock 1.5)
ICH - 1.05 (stock)
PCIe - locked @ 100MHz
PCI - locked @ 33.33MHz

My other question would be, why would you want to undervolt ram anyway?
The gains (read: amount of decreased power consumption) to go this route is minimal at best, compared to say, getting a lower-wattage processor and more efficient graphic card.

1 edit | Your reply lacks cons for undervolting for the existing hardware. My CPU is undervolted but I get a higher FSB.

Undervolting RAM would be a minimal difference in wattage. No need IMO. |

Sherwood, MI | The RAM is rated for 2.1v at 1066MHz so I guess I wouldn't worry too much. |

| You have a pentium d with a OCed card... their is no reason to undervolt ram unless you are trying to see how low you can go... just like overclocking their is underclocking too how low of a vcore can you get a cpu to run (even at dumb low speeds)...
It fails when you undervolt so put it back to where it should be, pretty simple...
P95 is hardcore stressing your cpu and ram... the games are not likely why it is crashing while games are not... |
