DFI UT P45-T3RS Living Review

E8600 4,250 8.5x500 @333/800 1,201 6-6-6-14
Now you might well ask why with 1600Mhz rated ram am I messing about with 1,200. For a while, it's all I can do. Posting using the 333/1066 strap/divider (giving 1600Mhz) , causes a hang with the LED showing 50

This is definitely memory or NB related. I've used the same timings as in previous 1600Mhz post adjusting only the divider and Trd (performance) timing. I've taken CPU Multi down to x6 to eliminate any CPU issues, but get the same result.
Have tried changing the options in Clock settinngs Fine delay from auto to relaxed to more relaxed. No improvement.


So I tried dropping the divider to 333/800 giving 1,201, so hennce the title of this post.
Everything is stable, just can't up ram to 333/1066:-

E8600 8.5x500 400 strap - 8.5x500 400/1066 1,333Mhz 6-6-6-14
Jimmy at DFI got back to me on my 333/1066 issue, suggesting I try increasing tRFC and/or trying 400/1066. Tried the tRFC on 1600 333/1066 without any change.

Was able to run stable using the 1200 settings listed the post above, only change Dram Speed.
Ran Prime with Large FFTs for an hour, without any issues.

8.5x500 400/1,333 1,667 6-6-6-14
So I thought I'd get cocky and tried the above clock.
In regard to my ram it's the first time i've overclocked it and was interested if it would run at 6-6-6-14 rather than the 7-7-7-14 on the box.

Dram Speed = 400/1333 giving target ram speed of 1,667Mhz

E8600 4,335 8.5x510 400/1,333 = 1,701 6-6-6-14
So this afternoon , I got a little more ambitious and upped the FSB to 510 putting Ram on 1,700Mhz

Had to take CS Timing back to 2N from 1N to get stable.

Work in Progress 40~50 Minutes so far , NB Ram stability needs tweaking.

Great job mate

That's a damn fine clock in it's own right

Tried the 1600mhz set first, benches makes an interesting comparison. Not much difference in 32M pi slight difference in latency. 50.4 on 1600 set 49.1 on the 1900.

Like the 1900+ nees tweaking.

Ta yes , a few quirks on the other straps but the 400 is working a treat. To say it's only 2nd bios , shows some progress from my DFI UT X48-T3RS experience

Am just starting to experiment running 4x1Gb of the Cellshock 1600Mhz. currently at 8.5x480 400/1333 1600Mhz but so far haven't been able to drop timings down to 6-6-6-14.

[supershanks]

I have 2 sets of the CS3222271 2GB CellShock DDR3 PC3-12800 1600MHz (7-7-7-14) So far benches & tests have been witth a single pair. So I'm interested to see what I can run 4gb at and what performance hit I take.

So I repeated the 8.5x500 400/1,333 1,667 6-6-6-14 clock. I needed to make two adjustments to get stability.
1) Up Cas Latency Time tCL from 6 to 7
2) Up Common Cmd to CS Timing from 1N to 2N

Benches



Comparison Original 2x1Gb
Compared to running a 2x4gb kit with quietr a lot higher latency, I'm quiet pleased with the result, especially as I picked up these kits for £64.50 each, looks like they've restocked & hiked the £ up by about 15% now.
