Default X48 Ram Advice

I am really not sure what I'm missing here, basically I can get up to 600FSB and use any ram setting I want with full stability, anything after that an I need to turn ram speeds right down to have the slightest bit of stability.

Now I am probably forgetting something basic here but I've seen guys with 700FSB screenshots and over 2K ram clocks.

Just a pointer really at what setting I could possibly be missing or forgetting would be really appreciated.

Hiya ObscureParadox!

Am sure there are much better people in this than me but since you've gotten no replies....

Are you booting at whatever your setup's capable of then raising the fsb further from within windows via setfsb? Pretty sure it's a must (at least for most people I'd imagine).

Are you sure the cpu's capable of 700+ fsb? I've never gotten anywhere close but think it was more due to the chip I was using.

What kind of NB voltage are you running? Try raising it a bit? What kind of ram and what vddr's are you trying? Iirc...bbse, psc or hypers should all be fine. Have you tried a different strap? Some boards seem to like or hate certain straps.

Another thing I've heard is that actively cooling the NB helps A LOT. Most people I've spoken with recommend somewhere in the -30 to -40C range.

If you're running a gigabyte board, you'll need to play with GTL's.

Here are the settings I used for 643 fsb on a rampage extreme:

Attaching a pic from some of my hyper testing...maybe it helps a little?

Good luck! Am sure you'll get it figured out (if you haven't already).
Best Regards,

Hiya buddy! Cheers for the reply. I got it sorted in the end :P

One of the main things was that I was seemingly too lose for the high clocks, I needed C7 to get over the 1900MHz limit as well as a couple of other things. Myself and Noxinite have been trying to see where we can get with max 32M stability now on the boards. I am stuck at around 1060MHz (2120) whereas his board seems slightly better.

Hi ObscureParadox,

So you are basically saying the ram won't go higher in frequency (or the chipset won't allow it) if the latencies are too high? If so, that's very good to know
May I ask if upping tRD=perf level helped ?
Cheers

Ps: I'm not using X48 but EP45T, that should be similar I guess

Bolc,they are totally diferent on ram oc and latencies.
The difference in max frexuency for the x48 chipset will be given by the nbb,on some it's better. Cold will influence this aspect .
Pl6-7 are for 2000 mhz +.
Some psc work really good on rex,6-9-6 PL 6 over 2040 mhz.

I can POST at 2300C7 with hypers @575MHz FSB, but that's no where near stable. Looking for high ram and high fsb (600+) that is stable in 32M seems to require a lot of tweaking to get it working consistently. Best I got working was 634 FSB with 2029MHz PSC through 32M.

That's an interesting challenge. The highest clock I was ever able to achieve on my REX was 1056 MHz 8-8-8-24 2T with the blue Cellshocks with Micron D9JNL chips. Over 1050 MHz achieving stability on my board becomes very hard.
What was your maximum clock in the end?

To really max out requires lots of GTL testing, tweaking and patience.

I think this is my best high fsb/ddr score, nothing spectacular for sure, anyway not so bad
for it I set only vNB, PLL, VTT and vDDR
scannick`s SuperPi - 32M score: 7min 49sec 172ms with a Core 2 Duo E8500

I'm curious, why did you use 3:5?
