help overclocking please..........
 

I have never had an Intel before, and it seems like there is a lot more to it than with AMD.

Anyways, right now I'm just trying to see if I can get a good cpuz run.

I set the vcore to 1.35v for a test run and left everything else on auto because I don't really know what else to do. I disable HT, overspeed protection, and c-state, and I set it to 1 core.

It crashed at like 3.3GHz, which just made me feel confused and clueless. I guess I need some coaching here. :Dizzy:

Thanks!!;)

You're just confusing yourself. Everything OC's the same way......just the nomenclature is different.;)

Maybe I am, and it probably is mostly a terminology issue, but I still need help.

dont set it to 1 core ;)

turn off all the crap and ht, disable speed step and all c states.

uncore multi must be x2 ram multi or higher, up to 1.55vtt seems to be okay, up to 1.6vcore is okay.

bclk starts @ 133

go to 136 - 139 - 142 etc.. - ....using just bios...

OK thanks Splave. :thumbsup: I just gotta get SetFSB to OC with I guess. I really wish there was a handy program for remotely overclocking/monitoring like on ASUS.

BIOS does a fine job

just got to play with it a bit

gigabyte ...doesn't have one...

I honestly thought I was done having to constantly go into the BIOS to make adjustments unless it crashes.

Wait, wut hardware we talking about specifically?

this is xpower right? use the OC panel gizmo that attaches to the board

X-Power with a 920DO. I dislike the little gadget thing.

EDIT:...........the gadget might not be so bad now that I found a good place for it and I don't have to hold it in my hand like a video game controller.

The tolerance of this board using the gadget thingy for increasing clocks seems pretty good.

Take note of the peripheral voltages at stock clocks then set them manually yourself in the bios, then start your oc process focussing on the vcore initially, then things like qpi/vtt later.

Not from a Gigabyte mb but you can start here if you like...

Thanks guys. :thumbsup:

My board is an MSI X-Power Big Bang. Here are the main BIOS screens that I have questions on.

I think I see the reason why it crashed @ only 3.3GHz........probably due to the memory timings being too tight.

The following is a list of safe voltages given to me, but I'm not sure which ones some of them are in my BIOS.
EVGA VDroop Control = Without VDroop
CPU VCore = 1.5
CPU VTT = +175mV (1.2 to start)
CPU PLL VCore = 1.845
IOH PLL VCore = 1.845
QPI PLL VCore = 1.40
Dimm Voltage = 1.68
Dimm DQ Vref = +0mV
IOH VCore = 1.375
IOH/ICH/ I/O Voltage = 1.575
ICH VCore = 1.225
I need to know which is the VTT for starters. And also which is the IOH PLL Vcore? And what is DIMM DQ Vref? I think I can figure the rest of them .

CPU VTT is also known as QPI/VTT and QPI/DRAM.....that doesn't help me.

qpi voltage is vtt

this....

Dammit I figured QPI was going to be VTT, but that leaves me wondering about other voltages.

One at a time I guess. I feel like a total clueless rookie here, :blush: some things are starting to make sense though.

Thanks.

1.55vCore
1.6vtt (board has bad droop, this will equal low 1.5's)
1.65cpupll
1.7vdimm
IOH and ICH you can bump up a bit from stock

I will throw XP on my xpower and d0 920 and join you in the struggle. What temps are you benching at?

Cool!:thumbsup:

Ummm...Real-temp says -7s....when I run prime it dabbles into the low single digits.

I have Tiny7 installed on this HD.....but I installed it on the CHIV and it just happens to work. Shall I reformat before I go any further?

prime is for ...ummmm

wprime1024 ....is for benchers...

I wanted to see 100% load temps. Prime comes to mind. I've never checked the load% while running wprime. I will now though.

Going to reformat that drive right after I eat.

New motherboard = fresh os installation with chipset & display drivers

I was about to and then Windows loaded unexpectedly so I figured I'd play around with it.

hey bro, played with it a bit, at -30c or so this will get you 5ghz as a base for cpuz benching :) turn qpi mode back to fast for other benching. Boot 220x21 and up in windows.

Then just go from there, boot up raise clocks 1bclk at a time and see where it freezes.....add 2or3 pci-e mhz see if it helps...add some vtt see if it helps....add some vcore see if it helps....then add some more pci-e mhz etc. 225 to 238 bclk was a matter of raising pci-e from 108 to 115.

You need eist enabled for turbo to be enabled for x21 multi.

Good luck man :thumbsup: drop any questions in the thread

Save your memory tweaking until last...you will be fighting on too many fronts if not.

Thanks I think I can work with that.....looks like I need to (EDIT:re-download) and reburn my Tiny7 though for some reason windows files will not expand.

OK here's a question for ya.....why does it drop back to a 12x multi?

I set everything like you said except for only 1.68v on the borrowed memory and it booted right up to ~4.6-some GHz, but now it's back down to a 12x before I could even take a screenshot.

I thought I read that I should have the DRAM voltage .05 higher than PLL or something like that......don't want to damage the goods. Know anything about that?


EDIT: WOW spi in 8.8 seconds first run.......that's like 2 x 1090T...........LOL

It's because you have EIST enabled...try it without it for effect.

Then I won't get Turbo boost though right? Hmmmm........

make sure
enable eist
disable c1e
enable turbo
disable OC stepping

Disable all cpu page options less eist. def need it for turbo

I'm pretty sure I had it just like you showed earlier Splave. Is the multi supposed to stay at turbo speed or 20 somehow?

QPI PLL a lot of boards do not have... when they do have it and it is not called QPI PLL it is called IOH VCCA 1.1v

IOH/ICH IO voltage is PCIE voltage. Some baords like EVGA link them. Some split it up as IOH PCIE and ICH pcie and some only offer IOH PCIE.

Sucks not everyone uses the QPI PLL because for me that had the greatest impact on BCLKing in my n00bish experience. (Then again the R3F didnt really need it, it would run up to 220BCLK on all auto settings :S) Higher it probably was needed.. I managed to hit an unstable 237 on it. But really anything past 222ish was unbenchable.

QPI slow link mode is only a good idea for CPUZ or if it allows you to jump to 5GHz. It seemed to have about a 7-8% impact on performance when I was trying the superpi 8M challenge a while back. (went from 1'30" to 1'35" IIRC). Try it I keep seeing people recommending it, but there must be something else to it then just enabling it.

I benched this @225bclk with 1.65 VTT....haven't really tested max bclk yet. Tomorrow for sure.

With this chip and turbo enabled for max multi....how do I get a validation when it jumps back to 12x while idling?

Load the cpu.

That doesn't seem like a very good idea when about to go for max cpuz.

Just noticed the little "XS Bench" button at the bottom of realtemp. It only loads the cpu @ ~13% for ~10 seconds. I guess that will work.

1.65vtt for 225mhz is too much...even 1.5 should work....im just guestimating..

Yeah I'd say it was too much, haven't had the chance to test my 920 cold (probably won't as the board only does 220 apparently)
But I can get 200 at 1.34ish, so 1.65 seems very high.

heh heh I thought I was a juicer :)

way to high a VTT for that speed. And if you are dropping to 12x multi disable EIST and CSTATES in the bios.
