KT7-Raid, MEMORY problems.

[funks]

Hello,

Is anybody else out there having problems with their KT7-RAID?
Basically, I've tried two different types of RAM..

The Corsair Value Select VS128MB133.

1 slot filled @ 133 MHZ - system is stable (tried in each slot, all okay)
2 slots filled @ 133 MHZ - system is unstable
2 slots filled @ 100 MHZ - system is more stable
3 slots filled @ 133 MHZ - system won't boot - black screen
3 slots filled @ 100 MHZ - system boots - but unstable

I do know that none of the chips are bad as they all work in single chip mode, furthermore - none of the slots are bad I've done the single memory test on all three slots.

Scratching my head why my board can't be stable.. Plunked down 512 MB worth of Corsair RAM (Note, these are not the value selects but the real deal). They are TOSHIBA chips, CM654S256-133. Corsairs Memory Compatibility webapp states that they are compatible with the mainboard (recommended). 2 x 256 MB Chips.

The answer to that question

1 slot filled @ 133 MHZ - system is stable
2 slots filled @ 133 MHZ - system is unstable - win2000 won't boot
2 slots filled @ 100 MHZ - LO memory drive setting - stable

All in all, the BIOS settings were CL3 for the RAM, and 8/10 NS setting.
(defaults)

HELP! By returning these under performing chips, I will only get 85% of what I paid (PC PROGRESS - stated in their policy), that really sucks.

My system is as follows,

KT7-RAID with KT7-UL bios
SB LIVE on PCI 4
Asus V7100 Geforce MX 32 MB on AGP slot
SIIG Firewire Card (Slot 6)
Adaptec 2940UW (Slot 3)
300 Watt Power Supply (Sparkle Power Inc AMD approved)
FOP32-1
Arctic Silver
AMD Athlon 1 GHZ CPU (Blue core) not overclocked..
Win2000 SP1
AMD Duron + Athlon Registry Patch Installed
Microsoft VIA Registry Patch Instaleld


The test I used to verify stability was 3DMARK 2000 v1.1.
Instability == 3DMARK completely locks up, prime95 running on background
Stability == 3DMARK completes multiple passes in loop, prime95 running


CPU temperature is not necessary, 29 on idle and 40'ish under load.

Try changing the read latch delay, or something like that, it has auto, 0.5ns, 1.0ns, 1.5ns. If you have a lot of high density ram the delay must be set longer for stability. Its under the advanced menu I think.

Hello,

Well, it's stable at 100 MHZ but these are 133 MHZ chips.. PC Progress has a 15% restocking fee, either way.. I ordered 2 256MB CAS2 CT32M64S4D7E Crucial Ram from their website (even with the restocking fee taken out by pc progress - it costs the same, crucial is cheap right now). Should get here by monday, i'll let people know what my results are..

Funks,

Just got 256 MB of Crucial, my KT7-RAID has been super stable with it. I did have 128 MB of NEC memory... That was nothing but probs... Wish you luck with the Crucial!
