[MADMAX22]

I also run the ddr2 ref voltage at +2%.

[Ace-a-Rue]

I have a minor dilemma running Penryn on this board. I am not concerned about temps too much as I am in an unheated garage in NY in February and the ambient temp never rises over 15C.

OK,so here's the dilemma. The cpu runs Orthos for more than 4 hours on small FFTs. The RAM passes memtest 86 v.2.0 at the current setting. Orthos fails at 37 minutes under blend test. With each bump in DDR2 voltage Orthos fails a little sooner. I went all the way p to 2.274v for the RAM and failed blend test in 9 minutes.

Here are some voltages I am not all that familiar with.

CPU VTT = 1.13
MCH = 1.52
ICH = 1.09
ICH IO = 1.50
DDR2 REF = 0% (options are: +2%...0%...-2%...-4%)
CPU GTLREF 0%2 = 68%
CPU GT:REF 1&3 = 68%

Maybe changing one of these will help my blend Orthos stability?

Thanks -Jim

try 63-67% for CPU GTLREF...i read that the 45nm cpu's are designed to work at 63% for stock voltages...so...work from there up to 67% or 68%.

For the QX9650 & Q6600 I ran 69% as this was where the board (stock) was stable for high OC's, it's a matter of trying and seeing what works with your components.

the GTLREF and DDR2REF settings have always confused me

If the board is stable at:
DDR2REF: +2%
CPUREF: 70%

and also stable at:
DDR2REF: 0%
CPUREF: 67%

Then which is a better setting
There is no way to test which is better for my system if they are both stable so which should I stick with? Is there a rule of thumb (i.e. higherr is better) ???

[ncsa]

Well testing Memory with Memtest for each FSB/timing change will help, until you know where your modules operate within and also using your favourite OS tool .. be it Prime95, OCCT, Orthos and Games .. whatever you need for your system to run for you.

As for MadMax22, I have also used DDR +2 but generally when I am on the edge of the modules...

I would only bump the Ref when you need to and this tends to be when up start pushing the FSBs, the other voltages also play their part.

For the Q6600 cooling also plays a big part in 'stability'.

Like any OC, you can see what others have done but even identical part numbers will OC differently... so it is a matter of working your OC up bit by bit ...

What is the temperature of the chipset (the chip below the CPU) called in Speedfan/uguru?

I did the bolt mod and couldn't see if it was making proper contact with the chipset properly because of that pad (which I should have removed so I could see).

Also my PWM is always cold, like, 30-35c cold. I'm not too sure why some people are reporting 80+c? Never gets hot to the touch even when I max the voltage out on it. Unless the PWM isnt the thing to the left of the CPU?

Also what are other temps called in speedfan? I'm sure someone has checked all this out before !

Thankyou !!!

[BassKozz]

Hi guys, I'm trying to find out what these are called in speedfan:

- northbridge chipset
- southbridge chipset

Or how I can check the temps of these. I did the mod for the bolts and want to check if the chipset is OK (I couldnt see how far I was tightening it down!!)

Thanks !

Don't think the NB & SB have a temp sensor, could be wrong on this thou. Anyone know for sure?

Are you monitoring the PWM temp at LOAD or IDLE?
My PWM doesn't get that hot at IDLE even at high voltages, but when I load up my Q6600 using Prime95 it starts to cook
p.s. Yes, the PWM is the HS to the left of the CPU

[Texray1]

I have a question which may reduce some of you to tears of laughter. I'm still a nooblet at this stuff and I don't totally understand a lot of what is happening inside my case.

If I am assuming correctly, since I can touch my heatpipes with power on, they don't appear to have any voltage applied. I assume that means they are at ground potential. So.....if my cpu cooling fan radiators were to be too close to the southbridge radiators....would that be bad?

I know this isn't specifically a question about this board, more of a general question. But you guys are terribly knowledgeable and I don't mind sounding goofy as long as I can add to my brain's database.

And it idles 2 degrees lower.

Thoughts? :p

[BassKozz]

Thoughts? :p

What processor are you using ? Are you OverClocking? What are your Voltages?
Also that's after only 3minutes of Orthos... you should give it a good 15minutes to get LOAD temp readings.

FYI For Future Reference: You should put your system spec's in your signature so that people can better assist

Thanks for all the replies guys. The below seems to have worked. Thanks Ace

I set this to 65% and so far, so good. Does this mean that I will want to increase this whenever I increase vcore?

Maybe someone can give a quick explanation of what each of these extra voltages actually does?

DDR2: 2.12
CPU VTT: 1.32
MCH: 1.50
ICHIO: 1.10
GTL REF: 55/54%

hey!...after looking at the above post from another
fella poster, it got me thinking about the CPU GTLREF
settings..smell it burning!

anyway, i started to fool around with those settings and i was
able to do 4.2ghz using 61% CPU GTLREF...

i read in an intel document recently which stated the CPU GTLREF for 45nm was 63%; lower than the 65nm processors, which i think is 67%...not 100%
certain on the 67%...but thought it was interesting to post this tidbit since the 45nm processors are not cooperating in the voltage department like the 65nm processors do.

[Nervous]

Guys, could anybody explain physical meaning of that GTLREF values (67% and etc)? Unfortunately, my E8400 can't work on FSB above 480-485 MHz: whatever I am doing, it fails in Crysis even if I set 500x6 (though in most other tasks it works, only crysis is picky). I increased all voltages, core up to 1.45, MCH up to 1.70, VTT up to 1.40, ICH/ICHIO also was increased - no luck. Motherboard & memory can do 500MHz - my previous E6750 worked as 500x7 solid as a rock. Now I have to use 480x8.5= 4080, which is not bad at all, but I want 500 FSB Do you think that GTLREF setting may help? What is the meaning of these GTLREF values?
My mobo: IP35 PRO 1.1, BIOS 16B09, Mem G.Skill PC2-8000.

it is a percentage of CPU VTT...you are suppose to maintain a 63% value of CPU VTT...CPU GTLREF is a sub-voltage that works in unison with CPU VTT.

what CPU GTLREF % are you using?

[Nervous]

I tried 67%, 69%, 61% and 63% - no difference at all... Looks like my CPU has low FSB wall

[stuck]

hello i test a E8400 with my IP35 Pro (bios 16 B03), and the cpu runs stable at 487x9 (4385mhz) 1.520Vcore (cpuz, uguru) 1.625V in bios, but i boot with 500x9 (4500mhz) with 1.57V, MCH:1.52V, ICH 1.09V, CPU VTT: 1.42V ICH0:1.55V, i have a question, for more stability at 500fsb you need a more ICH and ICH0???, greetings...

Whats the MAX. FSB done on a E8400/E8500, on the IP35 Pro?

[Bastard-Nation]

I have an IP35 Pro board and instead of using the standard cpu cooler that came with the q6600 i bought a Tuniq tower instead.

Installation was nearly done but then i realised the CPU fan header on the motherboard was a 4 pin connector and the one on the Tower was a 3 pin.No problem i thought i will just buy a 3 pin to 4 pin fan convertor as their are bound to be cheap and easy to find.

There are lots of 3 pin to 4 pin convertors but the 4 pin is a large Molex plug but i am after the small 4 pin like the one on the cooler that came with the CPU.I realise i can plug the 3 pin on the tower to any other fan header but i would prefair to plug it in the Cpu fan header.

Any ideas were i can get one.?.shops in the Uk would be ideal.

Thanks for the help.

I can do 525Mhz before my ram craps out. standard DDR800 stuff

BassKoz - E8400, 4050Mhz stock volts, (450x9.)

Also that temp just 'hovers' and goes up by 1-2c then back down, etc. It's just strange it runs cool compared to everyone else who needs to have fans on em.



Bastard-Nation - plug the 3pin into the 4pin plug. It'll fit in, look where the groove is and put it in, skipping 1 pin obviously. (I think you leave the far right pin out of it)

Has anybody had that issue after flashing the bios, that after you save settings, it starts to reboot, shuts down, powers up, shuts down (fans spinning turning on and off repeatedly)

I always seem to have this problem every time I flash the bios. I always seem to fix it eventually, but I can't remember what fixes it. Sometimes I think getting into windows and loading up uGuru does the trick, or it might be the fan monitor shutting it down.

It's like the bios gets in an unstable state, but once you are able to save settings one time, it never happens again.

Anyone have any ideas what causes this bug?


Thanks in advance!

I have a TT 120 with a 3 pin connector plugged into the IP35's 4 pin connector & it works fine.

does this happen after clearing CMOS using the switch on the I/O panel with the power cord unplug from the PSU?

4 pin fan headers are backwards compatible with 3 pin... meaning you can plug your 3 pin into it just fine. I wouldn't use a 3 pin fan on the 4 pin header on the Abit board though. That header is for PWM and in Abit EQ it doesn't let you set a voltage for it. Use one of the AUX headers for it.

[Scope666]

Yes, I clear the cmos, and flip the power switch on my power supply off and then press the power switch to discharge the caps.

It just doesn't want to save bios data properly the first time. Once I get the magic combo and save settings, if I'm able to boot once the problem never happens again. I can go into bios and change settings without any problem as long as I get that first save to "stick"

[mysticwizard]

i have a guestion about CPU GTLREF. I have my cpu running at 3304mhz. (8*413). the CPU GTLREF is still at 63% in bios (stock) should i increase/decrease this? Why should i do this? Could there be danger if i don't change it? :p
