ASRock 939 Dual SATA2 Memory Failures

Run Prime95 with the "Blend" option for about 6-12 hours, if it doesn't error out, than f*ck MemTest. I got the same problem w/ my RAM, it errors in MemTest and runs Prime for 16 hours w/ no errors, and I haven't ever got 1 Blue-Screen that wasn't caused by Overclocking. Run Prime95 and see what happens.

PS: It MAY be the CPU, but that's a bit out there

Check the memory settings in the bios. Also remember with the newer bios updates that the board sometimes defaults to the wrong RAM speeds. If you overclock--well kinda like what has been said before: memtest doesn't work well on OCed systems.

Reset the bios defaults, save and exit, THEN set the bios settings to how you need them to be set. You have BIOS ver. 1.6, right?

I'll give it a shot tonight and let ya know. Thanks!

BTW, Brucey-bourgeoisdude, what brand/model of memory are YOU running on YOUR board?

Oh...terribly sorry. My sincerest apologies...I didn't know.  

BUT then again, at least YOUR'S works! 8)

There is one quirk in memory speed that I have run into. I am running an Opty 165 on mine overclocked to 2.3ghz. My memory is 4x512 Mushkin Level II black winbond BH-5. for some reason the board does not want to run faster than a base clock of 167 with 2 gigs of memory. That said if your memory timings are tight 2-2-2-5-2t you can still fly. My dhrystone is 21477 whetstone 9828 integer is 45575 and floating point is 49194. If you are trying to lock 200mhz in your bios settings, that will produce this. The ULI chipset seems to be overly sensitive to memory quality. I have only had good success with BH-5, UTT CH-5, and TCCD. Mushkin is still selling UTT BH-5 under part number 990927. Yes it is DDR333 but with voltage that doesn't matter and with the way this chipset seems to work best you won't care anyway.

I bought it in early december last year---before I joined TG Forumz  

Casewhite:

Once I get my eyeballs uncrossed, I'll try to figure out what you were trying to tell me.

 

JK. I'll keep that in mind if I fail utterly. I was TRYING to keep this box around $600, but I might bite the bullet and go for a higher end board. If so, I'll avoid the ULI chipset.
