WTFUAR Posted December 11, 2004 Share Posted December 11, 2004 Hello, I bought 2 of this Corsair Memory: CMX512-3200C2 XMS 3202v5.1. I plugt them into my brand new Abit KV8Pro 3-rdEye with latest BIOS and I was realy disapointed by the overclocking performance. They run as fast as my old TakeMS CL3! I tried max VCore/VDimm (1,85/2,80) and with worst stepping CL3 they even didnt hit 226MHz stable on a Clawhammer A64 2800+ (C0 stepping). If I run them CL2 after a while I get a crash. Could someone tell what the problem could be? I wont believe that I spent a lot of money for crap. Link to comment Share on other sites More sharing options...
Wired Posted December 12, 2004 Share Posted December 12, 2004 Is that 266 Mhz as in (2x266 = 533 Mhz DDR) or 266 as in (2x133 = 266 Mhz DDR)? Normal DDR is 200 Mhz as in (2x200 = 400 Mhz DDR). If the former, then that's a great OC, of the latter then there's something going on (obviously). Is it running by itself? Have you tried it in other slots?

WTFUAR Posted December 13, 2004 Author Share Posted December 13, 2004 Well I said 226 not 266. And 226 with CL3 and worst timings. This Board only has 2 MemSlots. I dont think it will be a difference if I switch the slots. The memory is now running on CL2.5 3-3-6 but I dont have made burn-in tests because I am afraid of a crash ^^. Corsair says this memory is for oc'ing and oc-friendly. And that means for me a bonus (what I pay for) to get some more MHz than specified.

Wired Posted December 13, 2004 Share Posted December 13, 2004 Ok... so do you mean 226 as in 26 Mhz above stock speeds? If so, they're doing higher than warrantied. Try 3-4-4-8 for stability. Link to comment Share on other sites More sharing options...
WTFUAR Posted December 13, 2004 Author Share Posted December 13, 2004 The memory dont run stable with 200MHz CL2.5 3-3-6 and 2,65 VDim. It crashs with no return quite fast at burn-in. Is this correct for a corsair (this one)? For the next test I'll follow your adviced timings on 226 MHz. Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted December 13, 2004 Corsair Employees Share Posted December 13, 2004 What slots do you have them in? And I would check with the MB maker for the latest bios and install them in slots 1-3 or 2-3 and set the Dim Voltage to 2.7 Volts and test them one at a time.

OC'ing it is useless unless it's stable at warrantied speeds. Try 2.7 like Ram Guy said, you may want to try 2.75 or 2.8 if 2.7 isn't completely stable.

WTFUAR Posted December 15, 2004 Author Share Posted December 15, 2004 It seems to me that it is a powersupply issue, because of some of the crashing symptoms. I'll stop running tests on stability befor i get myself a new and sufficiant powersupply. so far ... Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted December 15, 2004 Corsair Employees Share Posted December 15, 2004 Well I have seen a lot more PSU's cause problems in the last year, so that is a possibility. Can a friend help you test the modules in another system? Link to comment Share on other sites More sharing options...
