Im hoping i can get some advice in regards to my oc system which i built a week ago. Im good with pcs but new to overclocking so please bear with me.

My specs are

UD7 Mobo
i7 930
Corsair 6gb XMS3 (9-9-9-24)
HX1000w PSU
HD 5970
Corsair 256GB C300 SSD

My problem currently is that even though im stable in prime95 (yes my settings could prob be improved quite alot) when i boot the pc up i will

A. Get no POST bios beep (when overclocked)
B. 50% of the time will get the "failed overclock red warning screen" and will have to enter bios, f10... then boot into windows

Ive not had any probs with prime95 at my current settings though know i still havent done half enough settings otherwise id be booting without any warning screens 100% of the time and would have the bios beep

My current settings:
....

Also i'm a bit confused regarding my RAM latency settings. My corsair ram is rated at 9-9-9-24 but in bios its showing 8-8-8-20? If i look at CPU-Z it shows 9-9-9-24??

Am confused to if i change the RAM settings manually in bios or ifs actually setup correctly.

Everything else is left on Auto, QPI was also on auto till today though has made no difference from what i can see.

Any advice/help appreciated.

SB,

these are my suggestions:

BCLK FREQUENCY [200] <= Start from 180 first, and go up from there

VIRTULIZATION TECHNOLOGY [ENABLED] <= disable for now
PERFORMANCE ENHANCE [TURBO] <= change to standard

CPU VCORE [1.30000V] <= try to lower to 1.28 V or less
QPI/VTT [1.315V] (set to auto i can pass prime95 no probs, set to 1.315v i get BSOD) <= try to lower to 1.3 V or less
DRAM VOLTAGE [1.64V] (Cant select 1.65v) <= try to change to 1.66 V

about the ram, set the timing manually, easy option, with your numbers: 9-9-9-24 2T

you don't specify the cooler you use, this may be the issue, your system may over-temp very quickly at higher voltages and frequency.
What are your temps ?

Good luck, Jure Z.

What does it do? How likely is it to improve reliability?

CPU VCORE [1.30000V] <= try to lower to 1.28 V

As it stands on current settings (i.e. if im not changing anything else) going below 1.30000v results in BSOD when testing in prime95

QPI/VTT [1.315V] (set to auto i can pass prime95 no probs, set to 1.315v i get BSOD) <= try to lower to 1.3 V

IIRC the bios doesnt have 1.3v exact

DRAM VOLTAGE [1.64V] (Cant select 1.65v) <= try to change to 1.66 V

I know its only a tiny amount but is it safe to run more voltage than the RAM is rated at?

the BIOS will change your parameters and multipliers very agressively and make your OC system fail

QPI/VTT [1.315V] (set to auto i can pass prime95 no probs, set to 1.315v i get BSOD) <= try to lower to 1.3 V

use the closest available value then.

DRAM VOLTAGE [1.64V] (Cant select 1.65v) <= try to change to 1.66 V

I would say that 1.66 V should be safe, but it is your call Sir!

Also, do you have load line calibration enabled ?

Thanks, Jure Z.

Only reason ive left it as it is, is becayse 1.66v is highlighted in red, maybe just because its above the rated limit. Not sure

Also, do you have load line calibration enabled ?

I believe its on as standard? So yes its on its standard settings

Thanks, Jure Z.

It is, as standard its set to "standard"

**Lsdmeasap** · 03-28-2010, 10:48 AM

Re: i7 930 / UD7 Overclocking advice

1.66 Vdimm is fine, and actually this is normally the only setting that will get you closest to 1.65V. You are fine to use more anytime you want though, just be sure to keep QPI/Vtt within .5 of Vdimm.

1.64 often only gives you 1.62-1.63V which is why you will often see 1.66 suggested/used.

Please give me your full settings in a template from my signature and a link to your memory, then I can advise you on best settings for your intended overclock and hopefully solve this failed overclock warning issue for you.

In regards to Memory speed and timings and CPU-z, be sure you are looking at the right tab. In CPU-z you need to look at the Memory Tab, not the SPD Tab. If you are not setting your memory timings manually in the BIOS then you should, what you see on the left can be ignored as it is not always uses, so you need to set yourself if you want a certain timing used.

I'll help you more in depth, once you post us your full settings.

Link to memory. This COULD be a slight prob. I built 2 complete systems, one for me and one for my flatmate. We got our parts from different places, i assumed the RAM was the same but looking at the part numbers now there is:

TR3X3G1600C9 & TR3X6G1600C9

Im not sure which is in which machine and what the differnce is between the 2 sets :( Doing a quick search on google it would seem one set is a 3gb kit so im guessing it was just an error in the part number on the website as both kits are def 6gb

In regards to Memory speed and timings and CPU-z, be sure you are looking at the right tab. In CPU-z you need to look at the Memory Tab, not the SPD Tab.

Def was the right tab

If you are not setting your memory timings manually in the BIOS then you should, what you see on the left can be ignored as it is not always uses, so you need to set yourself if you want a certain timing used.

Dont really understand "timings" so help on this would be appreciated

I'll help you more in depth, once you post us your full settings.

Legend, Thank you :)

Re: i7 930 / UD7 Overclocking advice

Looks like your memory kits different only in the amount, the first model you give looks to be 3GB set and the second 6GB kit. Did you know you bought 3GB and 6GB, or did you get robbed? Sorry, I reply as I read. Are you SURE both kits are 6GB??? You would have to look at installed memory in taskmamager for each kit, or in the BIOS system info page (F9 on the MAIN BIOS Page)

Before I advise, I need to know for sure which you are using, can you post me a link to where you bought your specific model as well? If so, or not go ahead and post me a screenshot of the SPD tab of memset, then we can see what amount it is and what timings are stock programmed.

Then I will advise back, sorry for the hassles and delays!

Sorry for all the questions - Just like to know what im changing / what things do etc etc. I have read up alot regarding values for different things in the bios as im new to overclocking however the problem is everyone has different stories hence why i thought id ask you directly regarding some of the above questions. Hope this is ok and sorry to be a pain.

Edit: Maybe i should point out at this stage that im still using F2 bios. The other pc is using F6Test from Hicookie though i havent changed mine yet as i wasnt sure which one was the best. Just thought id mention this incase it was worth noting.

Re: i7 930 / UD7 Overclocking advice

No problem!

Uncore Frequency .......................... 3800mhz (is set to AUTO as above) << Set manually, 2x memory multi or above. Often at high Blck 2x +1 or 2x +2 is better (I use 2x +2 most often). Auto is using x19 which is too much [What is 2x2? Sorry this uncore freq confuses me..In bios doesnt it say things like 2:8 2:10 etc? Need to look again to check.....]

What 2x +1-2 means is this. Uncore should always be at least 2 x your memory multi, or above. So 2x +1 or 2x +2 is often used. In the BIOS the values are shown as x16, x17 and so on.

Performance Enhance ...................... [Turbo] << I find Extreme to be most stable ok to leave on turbo for now? I ask as im not sure what this actually changes

Yes, you can leave if you like, I think it will be fine

DRAM Timing Selectable (SPD) .......... [Auto] Expert, set each channel main timings one by one What too? 9-9-9-24 im guessing? Just want to be sure :)

Yes 999-24 1T for now

Load Line Calibration ................. [Standard] Level 1 I was reading in google that setting this to level 2 is bad for the cpu though cant seem to find out why though again im not 100% sure to what this does. I have read using level 2 is really good for increasing overclock potiential of the chip though at the same time isnt a wise thing to change?

Well Level 2 does increase voltage, some like it some do not, just personal preference I suppose. What it does is adds to Vcore under load, a lot sometimes. I do not like it myself, that is why I suggest Level 1. Level 2 would not increase an overclock, it just adds more voltage under load, something you can do manually and control by setting value manually and use Level 1 to keep Vdroop at a minimal amount

QPI/VTT Voltage 1.150v ............ [Auto] (did try at 1.315v) << This will need to be 1.32-1.4+ depends on your CPU and memory timings, but auto will use much more than you would that is why it works but 1.315 did not for you. I'd start at 1.35 and see if that works, if not you will need more. 0x00000124 BSOD's mean more hereSo when i get the BSOD ive got to quickly see what error code it chucks to see what voltage needs to be raised? Didnt know this *whoops*

Yes, often you can see it on the BSOD page before the system restarts, or in the error box vista/windows 7 brings up after you restart if you tell the box to show you more details.

0x000000124 More Vtt (124 in windows error message after restart)
0x000000101 More VCore (101 in windows error message after restart)

Re the above settings, i read that unless using crossfire/sli it was ok to leave the above on auto?

Yes ICH ones may be fine in auto, but often times IOH will need to be increased. Sometimes auto will be ok for this though, if you want to test be sure to manually set the stock value otherwise Auto may increase it anyway. QPI Pll, stock may be ok but I find a bump to 1.2+ often helps much with stability

hmm i feel rather stupid atm, isnt my memory multi x20? so twice that would be x40 uncore?? What am i working out wrong?

I do not like it myself, that is why I suggest Level 1. Level 2 would not increase an overclock, it just adds more voltage under load, something you can do manually and control by setting value manually and use Level 1 to keep Vdroop at a minimal amount

So level 2 must be real bad for increased tempatures? I want to reduce mine, not increase them so will leave that alone in terms of level 2 ;)

Right, ill be off to test then - Maybe ill even get a post bios beep again if im lucky :)

Edit: Well i will do after i know what the multi uncore thing is properly and what setting to choose lol

It is a case of 4 cores and 4 threads = a multi of 8 so x2 would be 16, hence why the +1/+2 would be the x17/x18 recommended setting? Is that how it works?

Edit2: Well ive applied the above settings, still no flipping bios beep... does it only come on when its standard settings? lol - Will have to do some tests to see if i get the red warning screen on bootup, and stability compared to before.

So guessing when alot of things are set to auto it could increase voltages which would increase in a BSOD? Suppose now i can start testing lower vcores again as last time i tried lowering this from 1.3000v id always get the BSOD though if im honest NEVER checked what error code it was and didnt have alot of settings in place so could of well been the VTT
