How should I set Cas Latency: 2-3-2-6 T1 in bios?

[Regs]

Kind of a newb question. I have corsair xms LL and I know where my RAM timings are in the bios but the only timing I'm familiar with is CAS. Then there is about 10 other types of latencies I don't even want to mess with. Which latencys should I change to make it 2-3-2-T1?

Running a K8V.

Thanks in advance!

CAS# Latancy: 2

RAS# to CAS# Delay: 3

RAS# Precharge: 2

Cycle Time: 6

That should do it..

Thanks a bunch!

Ah weird names they had:

TRCD= Ras to CAS
TRP= RAS Precharge
TRAS= cycle time


Now all I need now is to get my PC3200(at 2700 spec) ram to run sync with the bus without the usage of a divider.

That would be the 1:1 divider in P4 and A64 systems.

Odd, I thought it would be too. But it ran my RAM at 110 Mhz the first time I tried.

I tried every divider too, then booted, opened up CPU-Z and here are the results:

1:1 (200 DDR) = 110 Mhz
3:2 = 157 Mhz
5:3 (333 DDR) = 184 Mhz
4:3 = 146 Mhz
2:1 (400 DDR)= 183 Mhz


Is it because of the PC3200 DIMM running at pc2700 spec?

1. Is your bus speed set to 200Mhz? (The A64 uses a Quad-Pumped bus)
2. How do you mean "running at PC2700 spec"? Is the RAM underclocked (because of divider issues) or is the memory coded to 333Mhz? If it's the latter I would RMA because that would be a crappy piece of memory, no offense.

My external clock is currently running a 220. (10 x 220) and my memory is coded for 333 Mhz.

One of the PC3200 DIMM's I have installed is 12 months old and was suited for a 333 Mhz FSB like the 2500+ Barton. Even CPU-Z reads the RAM as PC2700 even though it can run at 400 Mhz and beyond. When I had the BIOS set to auto detect the PC3200(at PC2700) slowed the entire system down.

12/CPU divider at 220 x 10 (CPU) + 110 Mhz RAM on auto detect. 220 Mhz CPU with 110 Mhz ram = performance kill.

What kind of memory do you have? And have you tried updating the system BIOS? And from the looks of things if you have a 1:2 divider you should try that.

Corsair XMS LL 3200

I just recently updated to a new BIOS. I don't think the K8v comes with a 1:2 divider. Maybe I should go ask around asus.com.

Have you tried the memory to see if it works at 400Mhz on another system? Lots of other people are having HyperX work perfectly in that board so I'm thinking that your memory might be the culprit.

Good luck!
