[Sir Skully]

Hey Chuck, I've read on the net were guy's say, they get lower Voltage. By using the odd multi/21, rather then the even multi/20. I don't know if there is anything to it. But a higher multi like 21 should make it easier to get a higher oc. I changed my oc to 21/173 3600mhz just to see what I can get. Vcore @ 1.2v and QPI/DRAM @ 1.2v. Here's a screen shot of TurboV and the voltages I'm using. Yeah it my help getting off of auto voltages, and all or most settings to manual. I'm also running OCCT to stress this oc ......

Chuck here's what these same voltages look like on auto, cpu voltage 1.2875v and QPI/DRAM 1.2375. You can see a lower manual voltage will work.

might seriously consider water cooling if the temps don't come down after the AS-5 settles in.
I know I only let prime 95 run for a tad over 49 minutes but I think this cpu has more in it, cpu core voltage is only 2.5 here, I know there's headroom for more if it wasn't for the temps
anyway I guess I'll let it run at these settings for the rest of the morning and while I'm at work tomorrow, be a good burn-in session

Your welcome, and glad to help its part of the fun...
As for your temps they are a little high. But the AS-5 settle needs time to settle in. Hopefully temps will get better.

Thanks for the voltages. I may play around with it soon. The 21x does not change my memory timings. Same as 20x.

Have you tested changing the UCLK?

Hi chuckbam

I noticed that if I set bios defaults (which resets almost all settings to an auto) that it takes quite a bit more voltage to run the system at the same oc then it does if you went through the choices and manually set the real (standard) voltages for those same items. Might be worth a shot to get your Core voltage down a few notches.

Noticed that only CH-DATA of your Dram Reference voltages were adjusted in that screenie. was there a spicific tech reason that you didn't bump CH-CTRL the same? was just curiour is all

I let prime 95 torture test run for a good 8 hours now 3.8
temps are a tad high at full load 71, 69. 68, 69
but as soon as I ended the test temps went to 43, 39, 41, 40
I think the idle temps are very good, seems to be stable at 3.8

"manually set the real (standard) voltages"
Are you saying that you know what the reference voltages are? Could you please post them. I would rather set a volt than use auto.

Have you tested changing the UCLK?

DRAM Frequency and UCLK Frequency pretty much go hand in hand with each other.
Example: If you set your Dram Freq. to 1600 (which is what MY ram is rated to run, at a voltage of 1.65) then you would double the number for UCLK Freq. 3200
then head down to (current voltage) Dram Bus and set it at your rams rated voltage (1.65) which is what mine is rated to run at.

Now, I've been holding my ram back on my oc thus far because
#1 I was getting errors and one or more of my cores would stop working in Prime 95.
#2 I wanted to find my cpu's oc limit before I started to tweek my ram.

Explanation:
I used the (OC From Memory Level up) to get to my rams rated speed 1600.
RE2 automaticly adjusts the rest of the system for this kind of OC.
Latter I realised why I was getting my errors. I used TurboV to adjust my Dram Reference Voltages within windows, and instead up bumping the voltages UP a tad, I unknowingly reduced thier voltages to a slight negitive Hence my errors!

I'll start tweeking my memory now that I have the system stable at 3.8.

As for "manually setting the real (standard) voltages"
when you arrow down to your Curent voltages and you select for example CPU PLL voltage.
look to the right side window pane. most of the selections show the (Standard) voltage over there.
press your + key on the numbers pad 1 time and you'll have that (standard) voltage set.
go through the list at manually set the (standard) if the bios shows a standard for that selection item.
not hard really

There are a few websites that show standard and max voltages for a lot of these setting, I'll see if I can find them again and I'll post back latter.

I hope this was of some help chuckbam

[chuckbam]

Thank Exc,

I have the same bios option with the Standard and the + did set that. Except for the DRAM Reference Voltages. They list the "Standard" as 0.500. Does that sound right to you? I did not change them from Auto. But it looks like I am 0.500

I see that S Skully has them set to to a lower voltage.

You're welcome chuckbam

what bios ver. do you have?

Sir Skully, Dan-Baer, and myself all have the latest 1204 bios.

I'm not seeing a (standard) voltage for Dram Reference Voltages in MY bios.

I wanted to keep all my voltages as low as posible and still keep a stable OC (as does anyone of course)

So for Dram Reference Voltage I set them manually to +0mV
On Auto, they all jumped up simularly to what you are seeing.

As you start to oc your system. you will need to adjusts voltages and timming settings to keep things stable.

I have been lucky so far and have not needed to raise my Dram Reference voltages up from +0mV to keep the overclock stable at 3.8 thus far but that may change when I start tweeking my memory more.

Yes I've tried all the UCLK settings, and the only one that ever works, is the lowest setting for whatever oc your trying for. I've been busy today. If I'm a wee slow in answering that's why.

I don't have a Rampage. I have the P6T-D. I am keeping the Reference Volts at Auto for now. I will go check another forum and see what their V are. I have been running this OC for a good while now and am very comfortable with it. I am not really an pure "overclocker", but more of trying to get the best out of things. I like your perspective of keeping voltage setting as low as possible. To much on the net of just setting everything to the max.

I think my performance increased after manually setting the Voltages to the "Standard". Thanks, I missed that notation in the bios My UCLK was defaulting to 2x (2887 MHz). I moved it up one more to 3067 MHz. I had it there before for several months.

[Dan-Baer]

I've not had much chance to play the last few days, gotta give a talk at the IPC APEX/Expo electronics manufacturing convention in Vegas next week.
I have run the sensor test and Prime 95 for a few hours and my temps never get above 62C.
I am off to read the cooling link :-) I will post more tomorrow after I have a chance to try boosting the OC and tuning a little.

I just forgot to set the Dram Reference voltages. I'm not trying to oc the memory. I have Corsair 1600 memory so if I can keep memory @ 1600 I'm happy. A neutral setting say, standard/+0mV is fine.

*smack me in the head*
Now I feel real dumb!

I didn't even pay attention to your set up
I'm so sorry chuckbam. Gawd I feel silly

Good to hear from ya, was wondering how goes with oc. Those temps look good @ 62c......
