wherever you save it, default is baredit install folder!
Nah it wont cause any probs for reading. It just reads pci register space is all!

Looks like I don't have much luck with my E8500. Since I have EVGA 750i motherboard I only have positive values to set up. Tried with 40/0/40/0 and 50/10/50/10 with 1.35V in BIOS, actually 1.336V in load at 9x445 with FSB VTT at 1.2V (1.18V Everest says) and nForce MCP 1.40V, but Prime crashed with first core after 2 minutes...
With VTT 1.2V I get -0.038V that's way i tried combinations 40/0/40/0 and 50/50/50/10 for GTL ref values...
@ Cryptik
On my Board (P5Q Deluxe) i can set for example 0.635 as GTL Value. So if i want to find my right gtl setting how must i start to set this value ?
For example if i select a higher value 0.640 the GTL increases,right?
So if i am running 1.20V FSBTer i can try what?
I have an E8600 CPU.
Yes the higher you set the multiplier the higher the Vref you will get. To start with, set them both to 0.635x and work from there. I have found with both my dual cores they like the address bus GTL Ref (the second GTL Ref on your board) to be a little higher than the data bus GTL Ref, so you could set 0.635x and 0.655x for example. Test for general stability gains at several setting, and find the most stable setup for the given FSB & vFSB. I'm now running on my M2F 1.25 vFSB and the equivalent of about 0.690x and 0.70x on your board, it helped to stabilize my current clock.

Mikey, I have to agree with you about fine tuning with IBT, it's quite effective. The times & GFlops are very close and consistent when tuned correctly. I have noticed that the first iteration is always a little lower & takes longer though, this is not due to speedstep delay I have that disabled. This run isnt perfect but its pretty close:

Thank you Cryptik
At the moment i am running Both GTL's in Auto and NB GTL Auto but i want to get them manually to see if i can decrease a little Vcore and some other(if this was possible).
At the moment i am Running the CPU 420x10 RS 15 Passes of IBT.
I tried also 430x10 RS 15 Passes of IBT and 500x8.5 RS 15 Passes IBT.
Maybe i can play a little more to get higher FSB using a smaller multiplier.
The memories i have work very good the for the things i do, Crucial Ballistix Tracer Led Pc6400 @ 560Mhz with only 2.08V measured with Tester on the Board.
I will let you know when i make some tests these days.
Thank you.
Vincent
Agree with both of you guys, i tuned my GTLS (Thanks CryptiK :up:) and my runs are very close now

Sigh...Another problem...IBT Pass 20 runs that fails ORTHOS Large FFTs P9 in minutes...really disappointed and lost :shrug:
Does increasing vNB, raising the PL or increasing vdimm help? Is your system at least 1000% windows memtest stable?
Or NB GTL, this was what help by me, when i was testing for FSB. It's NB<->RAM issue and by me not even relaxed timing help, just NB GTL one (or two, if nessecery) steps up.
Well, using 2 days 1.8VTT on your Q9550 don't kill it, let's see if it affects OC ... *speachless*
I'd actually recommend using HCI memtest over bootable memtest, I have had ram pass bootable memtest that didnt last till 3% HCI memtest, and failed blend almost instantly.
It is found here: http://hcidesign.com/memtest/download.html
I assume you're running 2GB of ram so open 2 instances of HCi and set 860MB of ram in each and let it run till around 1000%. If you get an error keep tweaking your ram/NB settings. I also recommend making a custom run in Orthos of 4096K and letting it run for at least an hour.
If you can pass IBT then your cpu is at least quite stable, but running small FFT is also recommended.
Also do Blend in Prime95 it will find most memory / gtl errors and report as rounding errors. The severity of the rounding difference from what it should be gives you a rough estimate on the severity of the problem.
Small FFT tests L1/L2 cache mostly.
Large FFT tests small amounts of memory and L2 cache.
Blend tests large amounts of memory and copying between memory.
I find the custom run at 4096K FFT length I suggested is more stressful on the ram and NB than blend, but use whatever you want really stability is a subjective & personally definable thing.
OK I'll try the following tests and report back. Thank you guys...
1. Prime95 Blend: overnight
2. HCI Memtest 3.8...Quad run each 400MB for 1000%
3. ORTHOS SP2004 Small FFTs Priority 9
This step seems very complicated is this necessary to have a stable overclock like 4GHz on a licquidcooled i7 920
No. I7 doesn't use GTLs. it's for FSB only. I7 has its own architectually complex features you can get your head around though if it interests you ;)
Update: Small FFTs Failed 1 hr 4 mins, error in result, not rounding
CPU GTL: -30, auto, auto, auto
Okay I hate to say this but on three separate occasions I've decided I would try and get my head around it and set my GTL reg values to break the 4GHz on my Q9550 and get stable (Prime95 overnight blend stable but tend to get random freezes when gaming/browsing/idle) but I just get lost >.<.
I've understood the math behind it, but my problem is I have everything set to Auto except Vcore (1.4V in BIOS, 1.36V CPU-Z) and NB/SB (1.5V / 1.5V).
Current setup: Asus S2E w/ Q9550 @ 3.966GHz (1866FSB) - 1x2GB DDR3 1600MHz 7-7-7-20 (Need to RMA other module, doesn't pass memtest).
Other than the ram values set to spec and the voltage I've already mentionned, everything is pretty much on auto.
What VTT value would be a good one to start off with if I set it to manual? What's considered a maximum for a 45nm quad? Without this starting point I can't aim to optimise my GTL Ref values.
Any additional S2E/Q9550 info that one may know would also be appreciated :)
Considering I got this far with only touching Vcore and NB voltages I would assume I could break 4GHz, my goal being a FSB of 1920 :).
Stress tests can be weird. Some guys pass IBT and fail small FT, some pass small FFT and fail IBT etc. There's so many variables between systems I guess there's no specific rules. That's why I use every stress test I can.
Freezing/BSOD at idle but stable under load usually happens to guys using load line calibration (no vdroop) where under load the vcore rises slightly but at idle it's just one step too low.
I'd try setting your Vtt to 1.25v first and experiment with your GTL's and see what gives you the best stability. You can always work up from 1.25v as you test. From what I've read, around 1.40 - 1.42v for Vtt is about as high as most people go on air/water.
Some tests update again:
1. Small FFTs Priority 9 fail in 1 hr 4 min
2. Prime95 Crashed during overnight run therefore I don't know the duration
But one thing for sure is that the system is not stable still :shrug:
for IBT testing, 1.25v VTT will fail 1/10 runs while 1.2v can pass 20 runs. I wonder if vNB GTL is wrongly set (+60mv). Currently running 4x Memtest 3.7 (410MB each). Will report back ASAP after the result is out. I guess it's CPU GTL related but I don't have a clue still...comon:shakes:
:rofl: don't stress too much about it mate :D I've spent accumulations all up of weeks playing around with minor settings. Everything takes time I suppose.!
