XP4000 2Gb kit RedLine, doesn't do 260Mhz?


Recommended Posts

Hi, I've been clocking my system for a while now. When i bought my system i settled for running the mem ~450Mhz with 3-3-2-8-1T timings, but now i started wondering if they would perform better on high freq. but my problem is that i cant get them to pass 3Dmark03 on 260Mhz although i run timings of 3-5-5-10-1T... so am i stuck with the earlier setup, or should i try lowering the latencies and the freq?

 

is it btw ok to use software clocking utils? I havent used cos i just have a feeling it's better to do it from BIOS. but am i just being silly?

 

any other suggestions?

 

thx

 

(Picture of timings. vDIMM = 2.7-2.9, no difference)

To be honest, a lot of redlines just don't clock all that well. But to be honest on another point, i'm not at all surprised you got the results you did. The timmings in your screenshot bear no relation to any timmings i have ever seen, or ever run. Have a look in the OCDB and search for your ram, and have a look at the timmings other people use for them. Using windows apps to clock is not a good idea either, it's always better done from the bios.

Here's the timings that I used when I was running my 3700 SD at 9x324. I was using 2.92v (2.88v BIOS reading) DRAM voltage:

 

DRAM Frequency Set............................ - 166=RAM/FSB:05/06

Command Per Clock (CPC)....................... - Enable

CAS Latency Control (Tcl)..................... - 3.0

RAS# to CAS# delay (Trcd)..................... - 3

Min RAS# active time (Tras)................... - 8

Row precharge time (Trp)...................... - 2

Row Cycle time (Trc).......................... - 07 Bus Clocks

Row refresh cyc time (Trfc)................... - 14 Bus Clocks

Row to Row delay (Trrd)....................... - 02 Bus Clocks

Write recovery time (Twr)..................... - 02 Bus Clocks

Write to Read delay (Twtr).................... - 01 Bus Clocks

Read to Write delay (Trwt).................... - 03 Bus Clocks

Refresh Period (Tref)......................... - Auto

DRAM Bank Interleave.......................... - Enabled

Odd Divisor Correct........................... - Disable

 

DQS Skew Control.............................. - Auto

DQS Skew Value................................ - 0

DRAM Drive Strength........................... - Level 4

DRAM Data Drive Strength...................... - Auto

Max Async Latency............................. - 08

DRAM Response Time............................ - Fast

Read Preamble Time............................ - 5

IdleCycle Limit............................... - 16 Cycles

Dynamic Counter............................... - Enable

R/W Queue Bypass.............................. - 16 x

Bypass Max.................................... - 07 x

32 Byte Granularity........................... - Disable(4 Bursts)

 

My Redlines were running at 265 FSB. That is most I ever got out of them. The Infineon CE6 chips were generally good to about 265-270 and still 3D stable. Some people got them a bit higher. Most got about what I got out of them.

 

I have really liked my Infineon CE6 Redlines. They have done me pretty well. I'm currently running them at 258 MHz. I can't seem to get them much over 260 with the 4400 X2. I don't think the memory controller on the dual core can handle much higher than 260 FSB with the 2G RAM. At least I have not been able to get any cpu overclock stable when running my RAM past 260 on the X2. Still, my system performance is very good.

Tried your settings, but didn't work... :(

 

ok, so i've been testing a bit now, and tried the newest official BIOS and now running OCZ Tony's 704-2BTA BIOS. I have also tried the yellow slots, but that was even worse. I can't get them to work at 200Mhz with Cl 2.5 and 255 seems to be the max Mhz with any settings.. i think it's strange that almost everybody has got their sticks to do 265 and even 280.. i know that it depends on many different things and that you can't expect the same results as someone else, but i think this is really bad... the sticks should be really good at clocking... did i just have bad luck or am i doing something wrong?

 

Here's a image of the best settings that i got out of them, after this they aren't 3D-stable anymore... I HAVE done the clocking from BIOS, this only to show settings.

Please reply if you have any thoughts.

 

Thx!

Hmmmm.......might just plain come down to the differences between our two boards. The Expert was a newer board designed with running 2x1G RAM in mind. Your board was designed when 2x512 was the rage and most people were running TCCD RAM. I'm surprised that you still got not that very far with the 704-2bta BIOS. I think that OCZ Tony made 2 versions of that BIOS for each board. I think the other was named the 704-bta BIOS. Have you tried that one?

 

The only other thing is that your RAM might not just overclock well.

Try to get your CPU at 3Ghz instead.
