no workie 512+512+512+512, Asus A8V-E, 3200C2P2

[eean]

I ordered two 512 sticks of the Corsair TWINX1024-3200C2P2, to add to the exact same that I have already installed in my computer (so 512+512+512+512, 2 gigs total is the plan). Its an Asus A8V-E Deluxe motherboard.

 

Installed the new RAM. It boots fine into the Grub bootloader, however booting stops when it recieves a CRC checksum error when unpacking the Linux kernel. Reboot, happens again. I also notice that it reports different amounts of memory during the BIOS memory check, sometimes 2, sometimes 1.5 and sometimes one 1 gig of memory is reported (all without me touching the memory). Something is amiss. What do I need to do?

 

Currently I have it booted up using just the new RAM and its working fine ('old' RAM worked fine as well), so there's nothing wrong with the RAM itself I wouldn't think.

Please put the memory modules on either slots 1&3 or 2&4; make sure that you have the latest BIOS installed for your MB; load optimized/set up default, and set the following BIOS settings;

TwinX512 or TwinX1024-3200C2PT

Advanced CPU/Memory Configuration:

Memclock Mode: Limit

Memclock Value: 1:1 (DDR400)

SDRAM CAS Latency: 2.5T

SDRAM RAS to CAS Delay (tRCD): 3T

SDRAM Active to Precharge Delay (tRAS): 7T

SDRAM Row Precharge (tRP): 3T

2T Command Rate: 2T

Advanced CPU/Hypertransport

Hypertransport: 5X

Jumper Free/Frequency Voltage Control:

AI Overclock Tuner: Manual

CPU FSB Clock: 200

DDR Voltage: 2.75 Volts

All other settings should be set to default settings!Then please test them one at a time with http://www.memtest.org and let's make sure it's not some other issue! I would run the test for at least 2-3 passes to be sure!

Also, what is the revision of each pair? Make sure unless you have a Venice CPU core that your FSB is @ 333 Mhz.

I don't understand. You say "the memory modules on either slots 1&3 or 2&4". But I have 4 modules, so what does "the memory modules" mean?. And just to confound things you say to test them one at a time. :D

 

I have ran the memcheck86+ on the 2 new RAM sticks for ~9 hours with no errors. The 'old' ones probably went through something similar during the burnin from Monarch when I got the computer about a month ago.

I guess this means I don't have Venice, since I don't see sse3.

I tried to adapt my settings to those RAM Guy listed. Most of them were already set that way. I changed "SDRAM Active to Precharge Delay (tRAS)" from 6t to 7t. I couldn't find Hypertransport. Anyways, I didn't appear to have changed anything. I tried putting in the additional sticks and it worked the same.

With 4 modules you would need to run the memory at DDR333 and as was said before all 4 modules would need to be the exact same revision and part#.

Can you tell me our modules part# and revision of all of your modules (How To Read the Memory Label)?

[eean]

Hmm, I guess Corsair's online documentation lives in some sort of dream world. Basically from what it sounds like its impossible to get RAM for sure that works to add to an existing system. Anyways, I'll turn off the computer and see what revision and version my new RAM is. The old RAM is:

part # 0513031-0, version # 1.5

 

How do I clock it to 333mhz? Like I said I already attempted to set it to the BIOS settings you gave w/o success really.

[eean]

The new RAM is v4.2 and part 0520114-0. Guess I'll look into sending it back to Monarch, already put it back in its little retail case. What a waste of time.

[RAM GUY]

Well I am sorry, but its not suggested mixing memory. As most MB's now just will not tolerate slight differences in modules? And we have always suggested just one set of Twinx modules. If you really need 2.0 Gig of memory it would be best to find another use for the modules you have now and get a Twinx2048-3200C2 set of modules for best performance. Or you would need to match the modules part# and revision that you have. Sorry!
