Sarkk47 Posted September 22, 2008 Share Posted September 22, 2008 greetings, i am running two kits of TW3X4G1600C9DHX memory (4x2gb) in an asus p5e64 ws evolution. the bios version is 0602 and i have an intel q9550 non-oc'ed. in the bios under the AI Tweaker menu i changed the following settings (all other are on auto): DRAM Frequency: DDR3-1333MHz DRAM Timing Control: 9-9-9-24 DRAM Voltage: 1.60V i have tested the ram (each single modul and all four of them) with memtest and it did 2 passes with zero errors. my problem now is: i can install vista ultimate x64 without problems (i have to remove 3 modules for that), but once i install SP1 and various drivers (chipset driver x48, intel matrix manager) vista wont boot anymore. it gives me a BSOD before i even get to the logon/welcome screen with the following error: STOP: 0x0000007E (0xc0000005) and goes into an eternal reboot/BSOD loop. when i turn the computer off completely (pull the plug) and turn it on again, it usually seems to boot just fine. reboots from vista itself are also fine. just when i cold boot it the first time it seems to produce the BSOD. (and needless to say, it does not happen with only 2 modules equalling 4gb ram.) so my assumption is the settings for the 4 up configuration arent ideal and cause the BSOD when booting vista. im not an expert of ram timings and various other settings and i dont want to fry my mainboard by overvolting it. i dont want to OC the cpu (4x2.83ghz is fine) or the FSB (1333) and id be perfectly happy if the ram runs with either 1333 or 1066 as long as its stable. i would appreciate any assistance in this matter and be very glad if someone could point out bios settings to make the 4 up configuration work. the entire system (cpu, gpu, northbridge and mosfets) is equipped with waterblocks btw.

Corsair Employees RAM GUY Posted September 22, 2008 Corsair Employees Share Posted September 22, 2008 With 4 modules I would suggest setting the memory frequency at DDR1066 and set the memory Voltage to 1.7-1.90 Volts and set the NB/MCH/SPP Voltage to +.05 Volts as well and test the system with http://www.memtest.org. In addition, with some MB's (Mostly ASUS) you have to disable legacy USB in the bios when running any memory test. Link to comment Share on other sites More sharing options...
Sarkk47 Posted September 23, 2008 Author Share Posted September 23, 2008 thanks ramguy, that did the trick. increased the DRAM voltage to 1.7V and the NB voltage to 1.31V and the BSOD is gone. did two passes of memtest as well, zero errors. ram running smooth and fast now as DDR3-1333. (i was reluctant to experiment with the voltages myself because i once fried a mainboard by overvolting. granted, that was like 10 years ago but i am still haunted by it.)

W2k Posted October 20, 2008 Share Posted October 20, 2008 Another success here - I've got an ASUS P5E64 WS EVO with a Q9650, also non-oc'd, and 4x TW3X4G1333C9DHX (8 GB total). BIOS version 0506 (the latest official version according to ASUS website). Memory was not auto-detected correctly by BIOS so I entered the settings as specified on the packaging: DDR-1333, DRAM voltage 1.60V and 9-9-9-24 latencies. With this configuration, MEMTEST passed all four modules, Vista 64-bit installed correctly and the system seemed stable, but I soon started seeing random hangs (no BSOD, the system completely froze) about once per hour when playing games and sometimes during regular Windows usage. I used the same settings as Sarkk47, increased DRAM voltage to 1.70V and set the NB voltage to 1.31V (+0.06V increase). Since then I've used the system heavily for two days (lots of gaming) and it has been almost perfectly stable, with only one freeze (not sure if it was the RAM though, could be ATI drivers as I've also had problems with those). If the system locks up more I might consider increasing the voltage further. RAM GUY, any suggestions? Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted October 20, 2008 Corsair Employees Share Posted October 20, 2008 I would try and set the memory frequency at DDR1066 if that does not solve the problem. Link to comment Share on other sites More sharing options...
W2k Posted October 26, 2008 Share Posted October 26, 2008 I would try and set the memory frequency at DDR1066 if that does not solve the problem. OK, here's an update: Since I was still getting the occasional BSOD I changed the memory settings back to auto in BIOS (DRAM voltage at 1.70 and NB voltage at 1.31 still). This seems to have set the memory to DDR1066 and CAS 7-7-7-20. Strangely the system now seems _much_ more responsive, previously Firefox would hang for 10-15 seconds on occasion, this seems to have completely gone now (I thought it was a HD problem, guess not). I also left Memtest on overnight, all tests passed. So I suppose the verdict is, with 8 GB these modules can't do DDR1333 stable, at least not on any settings I know. A bit of a shame, really. :confused: I still get BSODs (THREAD_STUCK_IN_DEVICE_DRIVER) in some games though, but it seems to happen less often than before. Damn ATi and their drivers - still waiting for a response from their tech support. Only seems to happen in newer (DX10?) games. Should anyone have a clue regarding those BSODs, feel free to drop me a note. Link to comment Share on other sites More sharing options...
DerekT Posted October 26, 2008 Share Posted October 26, 2008 Increase the DRAM to 1.75v (for 7-7-7-20) and the Northbridge to 1.35v. Set tRFC to 60 DRAM Clocks and the Command Rate to 2T. Also, if you have been having many blue-screens, you may wish to reinstall the OS due to very possible data corruption. However, I think you are correct about the thread stuck issue being ATi. Their drivers keep me away from their hardware. Link to comment Share on other sites More sharing options...
W2k Posted October 27, 2008 Share Posted October 27, 2008 Increase the DRAM to 1.75v (for 7-7-7-20) and the Northbridge to 1.35v. Set tRFC to 60 DRAM Clocks and the Command Rate to 2T. Pardon the n00bish question DerekT, but what would be the purpose of these changes? To improve stability (make ATi drivers crash less)? Also, I'm assuming that I should keep the frequency at DDR1066 (533MHz) for now, correct me if wrong. Link to comment Share on other sites More sharing options...
DerekT Posted October 27, 2008 Share Posted October 27, 2008 This will allow you to isolate the crash. If it is the ATi, then you can drop your voltages and if the crashes cease, then you are on the road. You may also wish to increase your PCI-e 5 increments. Yes, keep the bandwidth the same. You are trying to achieve stability. Link to comment Share on other sites More sharing options...

You are trying to achieve stability. I checked the settings and apparently setting them to Auto set tRFC = 60T and CR = 2T, so no need for me to change manually. I'll try bumping the voltages a bit more like you suggest and see what happens. Link to comment Share on other sites More sharing options...
W2k Posted November 5, 2008 Share Posted November 5, 2008 Flashed my motherboard BIOS (was 0506, now 0602) and the problems appear to have ceased completely. Have not had a single BSOD, freeze or suchlike since flashing and I've been playing CoD4 a whole lot (used to give me BSODs before). So far nothing conclusive but those of you with an ASUS P5E64 WS EVO might consider flashing to 0602 if you haven't already, apparently it fixes more than the changelog mentions (surprise)... Still using the same voltage settings, DRAM at 1.70V and NB at 1.31V btw. Everything else is on auto in BIOS. Don't see a need to tweak anything further while everything is stable.
