TWINX1024-3200XL on an Abit AV8 with FX-53


Recommended Posts

I'm also running TWINX1024-3200XL on an Abit AV8 mobo, with AMD 64 FX-53. I've been reading other posts with the AV8, and been trying everything recommended with no results.


I always run only the minimum required hardware to run windows setup. No sound card, no nic, only one stick of ram, etc. Mobo has latest bios.


Loaded stick one from TWINX1024-3200XL into AV8 slot 1, windows gives "setup cannot copy file xxxxxx blah blah blah". Stick 2 in slot one, same thing. Try each stick in slot 3, same thing. Test both sticks using AV8 and memtest, allot of red.


Pull a TWINX1024-3200XLPRO from my IC7 P4 3.2EE, load one into AV8 slot 3 (wont fit into slot 1, proc hsf), windows loads without a hitch. Plug the other into slot 4 for dual channel, all is well. Pull a TWINX512-3200C2 out of my P4 3.0 and load into slot 1 and 2 (smaller hs so they fit), all is well. So, slots 1-4 on the AV8 are ok?


Move TWINX1024-3200XL to my IC7 P4 3.2EE, computer not a happy camper. Test both sticks on this mobo with memtest, again, allot of red.


Now here's what's blowing my mind. I had another TWINX1024-3200XL for the AMD build on the way during all of this, arrived this morning. Did every combo as I did with the first set, same thing. Setup dont like them, windows dont like them and memtest dont like them.


Above is the condensed version.


Maybe I'm in denial, Ive been using Corsair XMS exclusively for all my builds/upgrades and never a problem, but I cant believe that I could get two bad sets in a row.

An update.


2-3-2-5 didnt work, so I set values at 2.5-3-3-7, which was suggested in another thread with the same problem on similar hardware. At 3 hours and 13 passes, no errors. But still, shouldnt I be getting the 2-2-2-5 as tested?


Just swapped out modules with the worst of the 4. Running test.

The worst of the 4 modules produces steady scrolling red, 4 digit errors in mere seconds. Tried changing values, reseating ram, no go. This was 8 hours ago. This set is going back to my supplier RMA.


Have had the second set on memtest at 2.5-3-3-5, 2.7v, 400mhz for 8 hours, 26 passes, no errors. Should I be getting the 2-2-2-5 these modules are rated for, or should I be happy with 2.5-3-3-5? I ask because I did some research and it appears the majority of pc-3200 out there is rated at or above 2.5-3-3-5.

2.5-3-3-5, 2.7v, 400mhz (actually 204/408 mhz) ran for 18 hrs, 55 passes with 0 errors.


I just set values at 2-3-2-5, 2.7v, and tweaked 204/408 mhz down to 200/400 mhz (what can I say, I like nice round numbers). Ill let you know how it turns out.


Curious, I went to the corsair website and looked up the test specs for the TWINX1024-3200XLPRO in my IC7 P4 3.2EE and the TWINX512-3200C2 in my IC7 P4 3.0C. The TWINX1024-3200XLPRO test specs indicate 2-2-2-5 for both intel and amd, but the TWINX512-3200C2 indicates 2-3-3-6 for intel, and 2.5-3-3-6 for amd. I'm curious why?


Thanks very much for your replies. I sincerely appreciate the input.

Does the c2-cas2-AMD thing have to do with the AMD memory controller being on the proc die? I thought moving the mem controller to the proc die was supposed to be the stuff.


Well, I played around with the numbers.


2-3-2-5 = 7 errors in 24 hrs.

2.5-3-2-5 = 3 errors in 24 hours.

2.5-3-3-5 = no errors in 13 hrs, still running.

All tests at 200/400 mhz and 2.7 volts.


Looks like 2.5-3-3-5 may be the best this memory can muster in this system.


Anxious to get the RMA exchange memory to see what kind of numbers it can post in this system.


Thanks again for the help.
