Page Faults

I have some OCZ Reaper HPC 2x2GB DDR2-1066 modules on a Gigabyte MA-770-UD3 Mobo. This mobo does NOT support modules over 1.8v but I bought some 2.1v memory anyways. (long story).

I was getting some BSOD (Page_Fault) at the standard settings. I got into the BIOS and I clocked up the voltage on the DDRII to .0750 (?) making the 1.8v standard, 2.1v.

The instability I was having was 'eased' a bit by this adjustment, however, after a little over an hour of Half-Life 2 at full settings, the game crashed out. I loaded MemTurbo4 to clear up the RAM and restarted HL2. About 20-30 minutes, this time, I got a BSOD:

"PAGE_FAULT_IN_NONPAGED_AREA"

BCCode: 0x00000050

yadda, yadda....


The Question: Am I at a loss with these modules on this board?
Secondary Question: I was asked about my PSU. It's a Thermaltake 430W. Based on consumption requirements of this build (roughly 280W), this PSU should be adequate.



System Info:
Gigabyte GA-MA770-UD3 (Updated BIOS)
AMD Athlon 64 X2-7750 KUMA 2.7GHz
OCZ Reaper HPC 2x2GB DDR2-1066 (8500)
WD 500GB SATA HDD
EVGA nVidia GeForce 9800GT (512MB)

For the PSU, are the rails stable? Do they fluctuate?
I would also do memtest (overnight) www.memtest.org and also OCCT to see if the system is stable.
If it don't pass the memtest, then don't bother testing with OCCT.

I would say you need to fix those two things before doing anything else.

He needs to dump the MB, because the OCZ "REAPER" name is just too cool not to keep it.

If only I were so shallow

The memory is good stuff. There's been "RAVE" reviews about G.Skill, but just the name alone scares me away. Of all the reviews, here, TH, NewEgg G.Skill is heavily mixed and it's all one-side with OCZ. I've been loyal to Crucial and Mushkin in the past.

I just placed an order for some mushkin 4GB (2 x 2GB) 240-Pin DDR2 800 (PC2 6400) - Model 996587. Latency is the same, timings are a little lower. The options for QVL from Gigabyte for 1066+ DDR2 modules is slim pickins without having a Phenom CPU. With this minor inconvenience though, the system as-is is Blazing fast (as well as inexpensive).

Nice choice.

That's the best cheaper 1.8v DDR2 2x2 GB kit you can buy :thumbsup:

Thank you. Mushkin has a great reputation and I plan on OCing with this RAM. I'm keeping my Reaper modules and getting a second matched set for future expandability-- if and when I make the move to Vista/Win7.





***UPDATE***I upped the DDRII voltage (on the board) to 2.2v and the BSOD have ceased! However, there is a "weakness" that I sense with this setup now. Seems like the pep is gone (or which never existed)... I did a comparison test with SiSoft Sandra '09 and my Memory and Hard Drive benchmark were "on-par" with similar systems. My 3DMark06 score was respectable as well. This 9800GT is one hell of a workhorse though.

I'm awaiting a PCMark score. I have the Vantage combo but I'm not running Vista so I can't get a REAL score with Futuremark until I make the switch.


At any rate, this setup is running smooth with the voltages maxed (for this board), but I'm not satisfied.

My last question has still gone unanswered. With the DDR voltages "OC'd" on the board, but at nominal voltages for the modules, are there any long-term side-effects?

Any voltage over 1.8-1.9v for DDR2 is "OC'd" (for argument sake).
Yes, there is long term degradation of memory when over-volted.
