How to enable PAT on Abit IS7 ??

I just got this board and I upgraded to the latest bios version 1.3 and I heard that Abit has found a way just like Asus did to enable PAT on the 865pe chipset. So my question is, how do I enable this through the bios? I know that Abit can't call it PAT because Intel wouldn't like that.. so is it called something else? What should I change in the Bios. I am running Dual Channel Memory Mode using 2 x Kingston HyperX pc 3500 if that matters. Thanks in advance for your help!

Well if you look on ABit's webstie they actually list the enhancements/fixes in BIOS 1.3. One of them is Game Acceleration. I bet this is their version of PAT. Do you see anything in the BIOS that says Games Accel? I just ordered this board too.

no I don't see game accel in the bios.. does anybody know where it is? and can you confirm this is their enabling of PAT..?

It's supposed to be in the new BIOS, which isn't installed on shipped boards yet, meaning you'll have to flash BIOS before you get that option. The same is true of both the Abit and Asus boards.

Yeah I upgraded the Bios and it's called "Game Accelerator".. the only bad thing is.. IT DOESN'T REALLY WORK!!!... You can set it to: Auto, Streetracer, SomethingElse, F1 (from slowest to fastest). I tried putting it on F1 (without overclocking) and I couldn't get past that screen on bootup where it lists all your IRQ's and devices assigned to them.. I think that's the screen after POST right?

So it looks like Abit doesn't really work too good with there implementation of PAT.

Plus I hear from people on the Abit forums that if you use an sort of divider for your bus/memory speed such as like 5:4, etc. then the "Game Accelerator" won't work. So pretty much, right now it's worthless.

Plus last night, I tried overclocking my 2.8c to 3024mhz (216fsb, 1:1 ratio), it booted fine into windows and all, but as soon as I tired to run Prime95 torture test, the test started and then immediately stopped with an error. It just said to check the log and the log said that it is most likely a hardware error or too high of a temp. But my CPU temp was 60c and my case temp was 43c so I don't see how that is too high of temps for Prime95 to run. Any ideas on what is going on here..?

mixer,
read the abit forums some more -- i actually haven't oc'd either of my abit boards (ic7-g and the is7) ... but from what I recall, earlier last week there were posts on how to get those game accelerator settings to work. but, i didn't pay too much attention since i wasn't needing it right then. i think they were enabling one of the game accel features and then changing another setting somewhere else and were getting pretty good times. But, again, I don't remember exactly but i bet you can find it.

yeah I hear people over there saying that the "Game Accel" shouldn't even be enabled when you are overclocking.. They are saying that all the game accel does is lower your memory timings.. and they choose to lower the timings themselves manually. I am wondering, how do you know what good benchmark speeds are for you? Like what is the standard that everybody says they use for comparing their numbers? I see all sorts of programs and need to know what program to run and what test to run in that program to get a score?

60C is very warm for a P4 overclocked that little....with a decent air cooled solution you should stay around 40-47C easily overclocked at stock voltages. How good is your case cooling and what hsf solution are you using?

right now I am using just a crapy old case with the stock intel hsf. But I should have my Thermaltake Xaser III and my SLK-900U with the Tornado fan in tomorrow or Thursday. But please take into note, those temp readings are from an Abit IS7 motherboard, and those motherboards are known to be 10-15c over what other boards like the Asus P4P800 reports.. so I think I am fine..

It sounds like "Game Accelerator" is pushing your memory over the edge. These chipsets are very hard on memory!

so do you think I can't use Game Accelerator, or should I try manually adjusting my timings of the memory..?

I'd do some benchmarks with "Game Accelerator" disabled and the memory at it's highest stable settings, then another set of benchmarks with "Game Accelerator" turned to F1 and slower timings, to see which configuration gives better performance.

July 1, 2003 10:27:17 PM

Yeah I can even get it to boot into windows with "Game Accelerator" on the F1 setting... people are saying it's my Ram.. but again, I don't know what timings I should use on my memory.. such as.. if I play with the timings or the vDIMM voltage.. I am afraid of frying my memory or mobo... is this possible?

what should some timings be for my Kingston HyperX pc3500 ??

And do you know how high I can overlcock this ram? Such as can I go beyond 216mhz fsb on this Ram? Or do I just need to use a divider like 5:4 to really get my cpu overlcocked?

I don't know what your stock RAM timings are. But if you have stock settings like 2-3-2-6, changing them to something like 2-3-3-8 would help.

Anyway, using the higher numbers adds stability, it won't damage a thing, but will cost you a small amount of performance.

You'll probably need to use a divider such as 5:4 to go much faster, and that will probably make the F1 setting useless.

can you kill any of your ram, mobo, or other components by changing the timings or voltages of your VDIMM?

Or will it just cause your computer to not start up and it WON'T hurt anything..?

You can make your computer temporarily unstable or unbootable by setting the timings too fast, slowing them back down makes them more stable. You can kill a DIMM with too much voltage, but using the available options in BIOS, this would be a fairly slow process.

Crashman - I think you should add some stock timing details - "normal" and over-clocked - to your FAQ's.

But Officer, I wasn't speeding - I was qualifying ...
July 7, 2003 6:05:54 AM

Mixerman, I have almost the same setup but with Corsair 3500. I couldn't get the Game Accellerator to work either. In fact it keep casuing spontaneous reboots. Hell I wouldn't even know what to set it on even if it did work. I mean which is faster, Street Racer or Turbo. I guess it's subjective. I ended up putting it on F1 and selected Normal, Disabled, Disabled. It was the only was I could get my system stable, especially when I overclocked. I'm already running my memory at 2-3-3-6 and overclocking my 2,8 to 3.1 so I'm sure any potential gains by PAT are far outweighed by my overclocking and fast memory timing.
July 7, 2003 3:12:48 PM

actually I did get GAT to work.. but this is my setup..

250/200 fsb 5:4 ratio, GAT = Streetracer, Enhanced, last two options = Disabled, Memory Timings = 2-3-3-7 (my memory default timings), vCore = 1.6, vDIMM = 2.6 (default)

I believe F1 is the fastest memory timings, Streetracer is the second fastest, so on and so forth. I couldn't get F1 to work for me at all.

When I ran the Sisoft Memory Bandwidth benchmark, I got a much better result with GAT enabled.. I am getting 5230 - 5300 scores on that benchmark right now with the above setup.

Can anybody join in and let us know if these scores are good... and if the above setup is good?
I am debating whether to go with the 230/230 1:1 ratio with GAT = Auto, or just continue using the above setup?? Not sure which is actually faster..?

They couldn't just have an option for Memory Acceleration Technology with options for enabled or disabled. No, that would be far too easy.
July 7, 2003 6:54:18 PM

I thought F1 meant customizable. Is it referring to the F1 key on my keyboard to like a F1 jet? If a jet, I wasn't aware we had an F1 fighter jet. Without a doubt Abit could have done a better job naming this GAT crap. How about Custom, Fast, Faster, Fastest? Simple and to the point.

Anyway Mixerman, I read somewhere that PAT could only function on a 1:1 ratio but you say you're using 5:4. Also heard you couldn't overclock and use PAT at the same time.
