Well my IC7 arrived. No mods yet. Vcore is REALLY nice and stable (Makes my old IS7 look like a sack of crap.) Trying 5:4 with my khx2700 dcddr 1gig set. (Relabled kingston chips... possibly ch5 or ch6. 2-2-2-5 works to 185mhz at 2.5vdimm... can go to 3.3vdimm and still stuck at 185mhz. Tried it up to 200mhz 2-3-2-6 @ 2.8vdimm and 220mhz 2.5-3-2-6 @ 2.8vdimm [the boost 2.5gives me makes me think it's not ch5, but possibly ch6. I'm just guessing though.])

Anyhow priming at 3.2ghz stock volts now on slk900a (with adapter) and tornado. Boosting up to 3.4 next, then 3.5, 3.6 etc till I get instable. Updates soon.

Hits around 2600 stock vcore looks like. Trying 2700 @ 1.575 min now (1.58-1.63vcore so far).

2.6, so you're underclocking? ;)

I'm sure you mean 3.6...if that's the case, very nice 1ghz overclock w/ the stock voltage...impressive.

edit: oops, misread the 2.8C as a 2.6C, my mistake :)

Sorry, 3.6 yes.

Not quite a ghz. Maybe on water with 1.7vcore I could hit 3.8ghz. But I think I'm going to settle in at 3.7ghz. I was hoping to get one of the nice 3.9-4ghz 30 cappers, but I can't complain. I got a nice price on this processor. I just wish the ram worked better with this board. 1:1 at 2.5-3-2-6 would be nice after a vdimm/vtt mod, but I doubt it's feasable for this ram.

Where did you get the chip from?

aye, my mistake. misread the 2.8C, still nice results.

PS: FMJ rules!

Yea, even if its a 30 cap, it doesnt meen much more...

But your chip looks pretty good(Better then mine, 3.2 at 1.7V...)

I'm trying 3800mhz@1.63vcore now.

Really sucks that I don't have any ram that would work well with this board. Starting to wish I hadn't sold my bh5's. ;)


Anyhow, I can't get ANY performance mode (turbo, speed racer, L1) to run stably at a decent ram speed. Do they make much difference? What is it that they do?

I think it's PAT-memory acceleration.

Lithan

CPU-z Says memory performance mode is enabled... that isn't PAT?

3800rebooted, but I think it's temps because I get the same thing at 3600 and 3700 at 1.63vcore. Primes for a solid 5-10 minutes then flat out reboots. My guess is it's hitting shut down temp.

When I get back from vacation I hope to try this thing under watercooling and see if I can't hit 3800-3900. Might even try the vdimm and vtt mods. I probably wont though, even with them I doubt I could get 1:1 @ 275 with this ram. (does 235 7-3-3-2.5 at 2.8vdimm... I wouldn't run above 3.3vdimm.)

the GAT (PAT) problem is common with IC7. I have never succesfully set GAT to any other setting that AUTO with my IC7-G, i've had 2 sets of BH-5's and a pair of OCZ 4200.

If seriously underclocked I managed to boot with turbo setting or so..

The GAT is improving the NB latency I think. So your RAM needs to be good and not stressing the NB too much to handle it, if it does not handle it, you will need to raise VDDQ....

The PC4X00 cant enable the GAT settings, but PAT will always be enabled on the IC7...

I think the concencous on what the IC7 boards like for GAT settings is A,A,A,D,D, correct? Try those if you haven't already.

Stock is: A-A-A-A-A, but lower is : A-N-A-D-D. Everyway, PAT is on.

And I strongly recommend having CPC disbled if you whant Turbo, SR, F1.....

My IC7 is set to A-N-8clocks-E-E, will not boot with the other two disabled like you posted. Is just that my Kingston HyperX sucks or what?

I can only do A-A-A-D-D when not overclocking. But mine will do A-A-A-E-E so maybe this relaxes the timmings? I do know first hand after testing 4 different kinds of PC-3200 and 3500, 1GB is much harder than 512MB to overclock at any setting.

Actually, E-E is way harder to do then D-D. I dunno whats the problem there.

And on my AI7(which I tought was the same everywhere), the stock is A-A-A-A-A.... But w/ newer BIOS it tends to be A-N-A-A-A

Mine will not boot with the last two GAT settings disabled, what up?

I have to run A-N-A-D-D to run my BH-5 1:1 at 250Mhz, 3.2V

I reflashed the BIOS to #21 I think it is(newest). I set it to A-A-A-D-D and it boots and at works, RAM is using 2.7v and processor at 1.55 as it always been. I can now boot into Windows, RAN Syssoft UnBuffered Mem 3885, better than the 3765 I was getting but the Buffered readings were slightly slower at 5410 instead of 5535MB I was getting, interesting. I have to run at 5:4, my Kingston PC-3500 will not go past 217 1:1. RAM's timings are CAS2 6-3-2-1T.

Thanks for all the help. I'm running AAADD now and testing my rams max speed here, once I'm done with that I'll see what I can get for actual usable settings.

I'm looking into picking up a IC7 for a friend but what is all those settings?

Actually, I can/do run 2.5-4-4-7 with Turbo on. It'll only do turbo if the rams set to cas 2.5 instead of 3 though. I doesn't seem to make a big difference though.

with my CH5 and 3.3v to them, vagp at 1.65 i can run 2-2-2-6, F1-N-3-D-D @ 235mhz...
