As promised, I did get the setup yesterday morning, but the problem was space in my flat. There is no room free anywhere at all. The E6750 SLA9V L726 1.350VID and from the choice of motherboards I chose a Gigabyte P35 DS4 rev1.1 F4/F8 BIOS for its known consistent high FSB and an Abit IP35-E Offlimits that was lying around unused I picked up too. Everything 'aint mine so I have to return working to my uncle who it belongs to. Two other systems I picked were older P4s and an AMD that Ill test soon. All standard air. One of the P4s died near the start and I don't know how or why since it was fully stock. I'm still thinking...
My god I hate long journeys for nothing.
The CRT monitor I picked up was so bloody heavy walking up 6 flights of stairs to my flat I have a crazy back ache that made me want to throw everything back out again!!
Anyway, I ran into hundreds of problems, the first of which was the monitor and its weird colors. I don't like the DS4 BIOS at all. Its too simple and lacking in a lot. I have no way of finding out what the NB/FSB voltages actually are, only what is being added on to them, nor any PLL voltage control. The setup wasted so much of my time because for 3 hours it wouldn't boot since the board set the VDIMM at 1.8V stock which I couldn't tell until I got into windows one lucky time. 1.85V was good for ~464MHz 4-4-4-12 and the RAM I wanted was taken by someone else so I'll have to go back this weekend or so to get it (Crucial Ballistix Tracer 8500). I picked up some PC2-Corsair XMS2 6400 CAS4 that was lying around v2.1 which are ProMos ICs I believe. Not supposed to be any decent but mine ran 2.05V DDR2-1160 5-5-5-16 500% (1600MB) Memset clear without error. They booted in Windows at 1262 at 2.3V which is +0.55V in BIOS for us to set,
I've still not tweaked them at all, just raised the voltages pretty high on most components to see where the limit on each is, the temps and the ability. Left timings to "auto" mostly.
This DS4 cannot do 500FSB. It can ONLY do 475 tops from BIOS at max FSB/NB voltages or even if lowered down many notches. No voltage added would change that situation and nothing is even warm to the touch so I don't know what the hindrance is or if I just got a dud board. It 'aint the CPU because I tested with x6 multi and with x8 I got 475x8 into Windows at 1.40V BIOS volts (never tried lower). It's unstable because the board is unstable at such high FSBs.
So I can't do runs of 600FSB 1:1 or 500FSB or even 475FSB 32M like many guys are doing, nor can I do 3600/1200. Max I can do at 3600 is 1125 (all in BIOS staying below DDR2-1200) and latencies are high. tCAS I can't even change to below 5 (not an option) nor change Command Rate and that doesn't matter on the temps or volts. I even tried +0.66V which is 2.46V real VDIMM at 1262 which was running at 2.3V before but no go. Not tried raising clocks within Windows using Clockgen/SetFSB yet.
First thing I did is run stock TAT/Orthos/OCCT testing. TAT was hardest on my system, topping out at 253W VAC stock 2.67GHz volts was 1.2V, ambient was 10C, and the setup ran very cool with a Zalman CNPS9500, a 40mm 6000RPM fan on the NB, open bench and a 12 inch powerful fan cooling the DIMMS/heatpipes all the way from Asia
EVEREST and Speedfan report the real temps and voltages accurately (I tested without a heatsink just to make sure) but Core Temp and TAT read 15C lower than the real temp at any time. Here's is TAT after 1 minute 100% load at stock. LOL its just so you get a rough idea of stock temps, I aint keeping it for use:
