is vtt the same as PLL
Printable View
vtt is know on some mobos as FSB Termination Voltage. PLL is completely different from vtt. On 45nm, vtt shouldn't exceed 1.4 as it will cause electromigration (cause the chip to slowly die).
L812B258, Pack Date 05/15/08 should be avoided, has a VID=1.25
hello which is better for the q9450
Gigabyte X48-DQ6 or abit ip35-pro?
This is my new toy:
http://forum.nexthardware.com/galler..._1_h_prime.jpg
Vid, according to coretemp, 1,25.
Vnb 1,29 volt, vtt 1,2 volt, fsb 1,6 volt.
It's an L815 boxed.
I've tested two of them and they clock exactly the same. :)

All test with Thermaltake Max Orb, AC5, is not the best cooler but for my quad is enough.
Temps in full load 63-64-55-65 at 3,8ghz
Later i will test more than 3,8ghz if i can do it.
Asus Rampage Formula x48
4x2GB G.Skill PC2 8000 (DDR2 1000)
Edit: I over-volted cpu vcore because I was experimenting with LLC for stability as there have been reports about instability on the RF.
oh yeaah i see too much v core in your quad, , re u using watercooling right??, but i see x48 is much better, if i put 3,91ghz like u my score in cinebench will be lower for sure, pretty nice chiset Zucker2k.
Iv been tested at 3,9ghz and i boot fine but my temps re a little hi, , almost 57 in cpu adn cores right 58 avg, but if y bench, ohh my god there s a barbaque here, all invited jajajajaaj
Looks like I just need to buy a real Rampage, and get a new Q9450...
Good results Zucker.
tnxs Zucker!, buy x48 is really superior, look at cinebench to much diference thats te good of your mobo, , exceleent performance.!
Plz can u post at 3,8ghz to compare in evereest test ans super pi. I can see the difference between x48 and p35 chipsets, obviously if u want!
Tnxs again men!!
Your welcome.... here is cinebench at 3.8Ghz... I posted this result here http://www.xtremesystems.org/forums/...=156129&page=3 last week. I'll run a 32m pi now and post results asap.
Thought I'd have a last play with this chip in the IP35 Pro before I start playing with the P5Q Deluxe -
http://img261.imageshack.us/img261/8931/superpiyl6.jpg
Not bad considering the VTT only goes upto 1.42v in this board.
Anyone running this chip in the P5Q Deluxe motherboard? I've got the following recommended BIOS settings for that board. I'd like to hit as close to 500FSB as my 'on air' setup can possibly take.

Hi, I'm new to overclocking, and I just got a Q9450. I got it to 3.2Ghz by only changing the vcore to 1.26 and everything else on auto, but after 2 hours of prime95, Realtemp reads that the max temps were 65, 53, 56, 60c. According to my thermometer, it's about 88 degrees in my room. I have a TRUE 120 and an EVGA 780i mobo. Are these temps too high? Do I need to remount the HS? or just try lowering the vcore? What's a good amount of time to run prime95 for ? Sorry for all these questions. I searched around and I'm still a little uncertain.
Those temps arent bad for air coooling in a 88F room. 65C is the max I would go so you are fine.
Welcome BTW!
Wow thanks! What a quick reply!
Uh oh, I just found out that I read the thermometer wrong. It's actually 78*F. Are my temps still ok?
Still not terrible. Remember, In Place small FFTs is 100% all 4 cores. in gaming and most other activities, you wont see those temps. In my PC its 10C less.
Do you guys use any application/software (like AI Suite, but something else) that stays on the Desktop reporting Clock Speeds, Multiplier, etc - CPU related information? I'm using RealTemp (System Bar) to monitor CPU Temperature & PC Probe to monitor Motherboard Temperature, Voltages & Fan Speeds. But I don't really care for AI Suite to keep mhz, speeds on the desktop.
Any Suggestion?
Everest.
It normale or a bug from Real Temp, he tell my cpu vid is 1.1625 , but I need 1.34V for 3.4GHz ...
Yep.. and if you are in vista, there is a gadget as well. :up:
VID, I thought, only shows what the voltage is for STOCK. It shouldnt have anything to do with overclock voltage. Someone please correct me if I am wrong.
Thats your choice. I use Everest, RealTemp and Coretemp (graphing feature is sweet). Mostly use RealTemp though just to check things out.
I think I'll stick to Everest & Real Temp.
Is there any critical benefit to Core Temp (aside from the Graphic that you mentioned)?
Its physically smaller... thats about it. RealTemp is better, IMHO, but I just like the graphing capabilities when Im benching/testing for temps.
Going to order one to use in a Gigabyte P35. Board can do 550FSB without a hickup with a 45nm dual core so crossing my fingers for some nice 1:1 action.
Can anyone recommend batches that have "more chances" of a good clocker? I can have the store choose a batch, but iirc, the VID on the box is always printed 1.25V MAX and a default for that kind of CPU. No way to tell what VID until you shove it in the board :(
A little review.
I'm coming from an E6420/2GB PC2-5400/P5W DH Deluxe and upgraded to a Q9450/4GB PC2-8000/P5Q Deluxe (P45).
This is all at Stock (8X334, 2667MHz), will be OC'ing this weekend, but wanted to compare Stock vs. OC performance.
I'm not impressed.
Sure, the system is flying in routine, regular operations like multi-tasking, boot up, opening & closing programs, etc. However, the true, labor intensive work is not showing big difference from my E6420.
For eg:- Did a video encode job last night. MKV -> WMV-HD (VC-1) 1080p (1920 X 1080) @ 11 mbps 2-Pass VBR / 768k 5.1 WMA Pro. Took about the same time it took before. I thought the SSE4.1, 12mb Cache & 4 Cores would make a noticeable difference. It didn't.
Un-raring an 8GB Archive took the same time as well.
The only difference was that during these processes, the system was more free & loose for me to do other things, hence multi-tasking galore - whereas before the system would practically render useless while doing these things.
Still, I was looking for more speed. Multi-tasking alone was neither the purpose for the upgrade, nor worth the money. So for my tasks & usage, at stock I'm definately disappointed.
I hope to OC it to at least 3.4 - 3.6, which gives me a good 1000Mhz over stock, and will take the Memory over stock as well. Hopefully I'll get better results then. Just wanted to put this out there, especially for video encoders because I know a lot of us went for the SSE4/12mb benefit in this chip over the much cheaper Q6600.
ohh goodie, just got my chipset coolers. I just need to go to the post office to pick them up first :)
As I'm about to lap my cpu cooler and cpu I'm wondering if I should lap the new coolers as well.
From what I have read online these coolers have a copper base and it is nickel coated.
What do you guys think? Should I lap the new coolers?
Has any one on here had any luck over clocking the 9450 with a GA-EX38-DQ6. I seem to be habing issues with it. I just bought the chip like 3 weeks go and I have had it to 445 FSB but, after that my board wouldn't stay stable. I'm thinking it's the motherboard. Thank's for your help any one. I almost read all of thses post but, wow alot of them..
You did run this test @ stock 2666 MHZ right? Was the previous system stock clocked as well? Considering you were on an 4mb cache chip, going up 8mb in cache and 500 or so MHz in speed, you won't see an incredible noticeable difference. Now try running that test @ 3.6GHz which your E6420 probably couldn't do on the P5W DH, then you'll see the improvement. Also consider that the 975X chipset is probably still faster @ stock than any chipset released since. Too bad the chip has trouble with that board though. I think you've not enjoyed the potential of your purchase yet until you oveclock it. Most intel cpus perform with 10-15% of each other @ stock clocks.
You're 100% bang on target. Believe it or not, I just had an identical exchange with someone else in the P5Q thread ... who's post resonated exactly what you just said. And I agree with you 100%.
Yes, this is all @ Stock. My E6420 was OC'd to 2.8GHz at which my board hit a wall (360 X 8), possibly due to my PC2-5400 RAM and the P5W 975X chipset. So you guys are absolutely right - I'm really comparing an 8mb increase in Cache, and that's about it! That & the better RAM is resulting in overall system boost, multi-tasking, but not actual result in CPU-Intensive processes.
I really should re-phrase the word "disappointment" because it's truly not a just comparison. And I really can't wait to overclock, which I will commence tomorrow. I think at 3.0GHz+ I'll begin to see the difference I paid for.
Thanks!

Hi, I've got a question. I'm running the Large FFT test in prime95 for my Q9450 (3.2Ghz) but it keeps freezing... after 11 hours, and then 5 hours after bumping up the voltage. None of the cores seem to fail according to the logs, but the computer freezes. Does anyone know why and what I should adjust? I've got a 780i motherboard, 2gb ram, TRUE120 aircooling. Thanks in advance. Also, I've got bad vdroop and I can't get the pencil mod to work. I drew couple lines over the resistors exactly as shown in the picture. 2B pencil, but got 1.26875 in BIOS, 1.232 in CPU-Z
Other info: Previously I was able to run prime95 Large FFTs for 16 hours stable @ 1.26875 until I stopped it, recently it's been freezing.
EDIT: I think I might have found the problem. My RAM was bugging out in Memtest86+, so I fixed that and am retesting prime95.
im watching some q9450 and p5q dlx oc results and that motherboard is amazing, or am i wrong?? hot 500fsb easy and cool, any body can tell thee experience???, i goona buy the p5q deluxe, but i need some recomendation bout this mother??
500mhz isn't easy.
Well it kinda is, but it needs high voltages.
Yeah it's a nice mobo.
How well does it clock in your P5K?

Addition The highest I have now got it is 460Mhz and I hit a wall on the board.. Ithink they need to get off their asses and make a better bios i what it is.
A lot of X38 boards won't get stable above 450mhz. My ASUS Maximus Formula X38 would only do 450mhz with my Q9450, yet the same chip does 500mhz easy in my P5Q Deluxe, and even did 480x8 Prime95 stable in my Abit IP35 Pro.
Hi there, I have a question: What does it usually mean when the computer freezes after 6 hrs of Prime95 Blend?
Not enough voltage somewhere.
what is a safe temperature to run this chip at under load? (air cooled)
I'm running memtest and my temps are hitting 63C @ stock speeds... should I re-seat my heatsink?
I'm currently running a Q9450 / P5Q Deluxe / TRUE combo and have been REALLY impressed by the stability I've gotten so far. From everything I read quads looked like finicky critters, but I'm sitting here typing this after 7+ hours of new prime (25.6.1.0) stability with 3.4 (8x425) & 425/4-4-4-12 - everything on stock volts except the memory at 2.1V :D. I do have a 40mm scythe mini-kaze fan cable tied to the nb heatsink which may be helping. I'm going to try to push it up to 3.6 tomorrow - if I have to increase the voltage at all to get to 3.6 I might just stick with 3.4, slap a 2nd scythe s-flex and turn all my fans down to 7V.
Max real temp temps while priming at 3.4 are 55-54-54-53. I'm using Shin-Etsu X23-7783D and was a bit worried about the application (spotty at best), but these temps look good to me. Could they be lower / should I reseat?
EDIT: Just opened up the case to touch the TRUE / NB heatsink - the eX-120 is much cooler to the touch than my oc'ed E6400 (which maxed at ~45C) & the nb heatsink / heatpipes are barely warm.

This is Awesome!! I was @ 2.8Ghz with my E6420/P5W/DDR2-667 setup .. and this is all out-of-box on stock volts. Stability is insane with the P45 chipset (P5Q Deluxe) and these 45nm Quads are ridiculous!!!
that mother is me next one, preety nice mother, moder, not expensive at all, stable.
Any body tested the las bios 0704 with q9450?? any difference??
This is my first post and any advise will be appreciated. Through the information in this thread and elsewhere I have been able to reach stability (24hr Prime95 blended) Q9450@3.7Ghz.
What I am concerned about is that the vPLL BIOS was set to AUTO and the BIOS says that the vPLL is actually 1.648v. I am now trying to lower the vPLL to the guideline of <=1.6v. Unfortunately none of the usual utilities (CPU-Z, Speedfan or ProbeII) tell me what vPLL is under load.
A test run failed after 7hrs with a BIOS setting of 1.52v with BIOS real of 1.616v. I just started another test run with a BIOS setting of 1.54v with BIOS real of 1.632v.
My bottom line is a 24/7 +3yr rig so with that in mind am I taking too much of a risk being +0.032v over the guideline target values? Also is there any other settings I can adjust so that I can lower the PLL voltage?
I am running a higher vNB than required but in the safe zone (BIOS 1.51v real 1.54v) and it is my next target to lower. Under load all of the temperatures are within reason especially if I can lower the NB voltage.
Other real under load voltages: Vcore-1.336 to 1.344, FSB Term (VCC): 1.28 to 1.30, vDRAM:2.16 to 2.14, vNB:1.52-1.55, vSB:1.07-1.09 All of these ranges are seen during a 24hr prime95 test session.
Assuming that I can achieve stability with 24/7 safety I will post all the gory details, I am just not finished tuning yet.
Thanks in advance.
EDIT: The test run with vPLL BIOS setting of 1.54v with BIOS real of 1.632v failed at 20hr 7min. The next BIOS higher setting is 1.56v with real 1.648v. The real 1.648v is the same real setting if you use a BIOS of "Auto" and at the AUTO setting I had a successful +24hr test run.
So I revise my question to be: Am I taking too much of a risk being +0.048v over the guideline target values? Also is there any other settings I can adjust so that I can lower the PLL voltage?
Not in the least!! :D
I haven't gotten to actual encoding yet, but I started a sample and before I even thought about doing something else while the sample was encoding - it was done! I couldn't believe it.
System is blazing fast - like I've never seen before.

They won't be much use to you as you've a different chipset :)
I'm using g.skill pc2-8000 ram and am currently sitting at 3.4 (8x425) on stock volts with 1:1. If I want to take things up a notch would it be preferable to go with 8x450 or 7x500? Would the higher speed / lower fsb be easier to stabilize or is 500fsb attainable without too much tweaking?
You'll likely find it very hard to run a 7x500 FSB without using high chipset volts. 8x450 should be possible on minimal chipset volts.
Anyone here running Q9450 @ 3666Mhz+ on Air 24/7 Stable?

@jas420221: That's what I'm hoping to achieve. Can't say I won't be happy settling for 3.66Ghz ... but I'd like to 3.8Ghz 24/7 Stable is possible at all.
Here is proof of a 3.7Ghz 24hr prime95 stable Q9450 on air. I am currently +16hrs into a stability test run to lower the vNB to 1.49v (real). If that passes the full 24hrs then I will have finalized my 3.7Ghz testing. The proof links where all done with a real vNB of 1.54v. My air components are in my signature. The ambient (room) temperature during this 24 hr run was 22-24C.
http://img369.imageshack.us/img369/9...SB_CPUZ.th.jpg http://img369.imageshack.us/img369/7...rm_Real.th.jpg http://img369.imageshack.us/img369/7...m_24hrs.th.jpg
I will post more details when my tuning is complete and successful.
Dude, that is awesome! I mean, seriously.
I can't say there is a drastic difference between 3.6Ghz & 3.7Ghz, but the fact that you have 24hr Prime95 stable @ 3.7Ghz and I have the same on 3.6Ghz makes the difference.
I've been trying to get that stability @ 463FSB like crazy - but it's just not working. I almost thought it wasn't possible on Air. Interesting thing is that your temperatures are absolutely identical to mine. So I'm not sure what's bottleneck(ing) my situation.
Any tips for me?

Thanks!
More NB volts is my suggestion. You have 4GB of ram and are trying to o/c a quad.
Yeah, I have been suggested (over in the P5Q thread) to up CPU Voltage to 1.400v and NB Voltage to 1.28v, so I'll give that a shot later today.
What's the max I should go to on NB?
Also, I'm wondering if 1.98v is enough for DRAM Voltage, or if I need to up that.
Lastly, I've been using a 1:1 divider. I wonder if I need to use a different divider.
I would say your memory is fine as you arent even running it at its stock speeds yet (500Mhz). So if 2.0v is stock voltage, Im sure you are fine on that.
For the test run that accompanied the pictures here were the settings:
CPU Voltage: BIOS:1.35v Real: 1.344v
CPU GTL Voltage Reference (??): BIOS: AUTO
CPU GTL Voltage Reference (??): BIOS: AUTO
CPU PLL Voltage: BIOS: AUTO BIOS Hardware Monitor:1.648v
FSB Termination Voltage: BIOS: 1.34v Real:1.28 to 1.30
DRAM Voltage: BIOS: 2.1v Real: 2.14 to 2.16
NB Voltage: BIOS: 1.34v Real: 1.52 to 1.55
NB GTL Reference: BIOS: AUTO Real: ??
SBridge Voltage: BIOS: AUTO Real: 1.07
PCIE SATA Voltage: BIOS: ?? (I will assume AUTO)
All "Real" quoted are under prime95 load. I saw ranges of voltages in some cases during the 24hr test.
The pattern I used to find stability was to raise the vNB as high as was safe and my cooling allowed, then step by step upped my Vcore voltage until 24hr prime95 passed. Then I went back and low balled the vNB step by step upping it until the sweet spot was found for 24hr stable.
I did that for 3.6GHz and now trying to finish 3.7Ghz. One other thing is I would have never reach a stable "safe" 3.7Ghz without the Pencil Vdroop mod. My Vcore would have been way too high, I know because I tried before applying that mod. Here is the link, it is only for some ASUS boards: Pencil Vdroop Mod - (I used a 3B pencil) http://forums.techpowerup.com/showthread.php?t=60341
You have to have allot of patience as I have had prime95 failures after 7, 12, 13 and even 20.5 hours. The 20+ almost killed me but I want to stick to the plan.
Assuming my latest stability test passes the 24hr mark the only "unsafe" for 24/7 voltage in my opinion is my vPLL (1.648) which is +0.048 over the guidelines I captured from this thread and some others.
I have queried on this thread for some advise but so far have not received any replies.
;p sub'ed
Some of the voltages you have are 'slightly' higher then what I'm using, but well within guidelines & safe limits. I think I'm going to give your settings a shot "If" I'm unable to attain stability using some other recommendations I've recieved in the P5Q thread (basically lower volts then some of yours).
The only one I myself would have pointed out - which you already did - is the vPLL, which is slightly higher then recommended. I'm not sure for 24/7 usage I'll cross any guideline - but if temperatures keep within limits, I'll certainly won't mind hitting the max "safe".
Yes, patience is definately the 'key' with Priming ... so is 'retries'. I'll give these few things a shot later today and hopefully tomorrow I'll have something better to report.
This is really helpful. Thanks!!
Edit: Do you keep Load Line Calibration ENABLED or DISABLED?
My Load Line Calibration is ENABLED. From what I read once the Pencil Vdroop mod is performed that setting does not matter much.
As for lower voltages on some of my setttings I tried many combinations. So far I have tried 42 test runs and 20th distinct set of BIOS settings. That excludes any settings/tests that could would not post or pass 10 minutes of prime95 and there were several of those failures.
Good luck
Edit: Last test just failed after 19hr 45min. Oh well have to up the vNB again and retest. At least vNB are still within safe limits.
I've got 2 Rampage Formula boards now & enuff parts to do another build soo I'm getting a Q9450 tomorrow for the 2nd build
got a QX9770 on the other
gonna water them both all over
Qx9770 is on the test bed now with a DD tdx water cpu block
I have had it up to 4 Ghz soo far
Wow, hats off to you. You're definately a patient man. :)
Two things that I've wondered about - one is of course Load Line Calibration. I've tried both ENABLED and DISABLED, and I really don't know if it made any difference either way, so I still don't know which one I should use.
Second is divider. I've been using 1:1, and I'm wondering if there's any reason I should deviate from it, and give, say, 5:6 a try! Not sure.
How can I do that? Sorry, probably a n00b question - but I really haven't dwelled deeper into droop.
So basically I should stick to a 1:1 divider till reach at least 500Mhz or above?Quote:

1:1 is always best. Running a higher divider, will net you results in benchmarks, but no real performance gains.
DL and install CPUz, on the first page, it shows the voltage, then fire up P95 on all 4 cores and watch the voltage droop, thats vdroop and LLC attempts to eliminate that.
Sounds good - I'm not looking for benchmarks - so I'll stick to 1:1
I have CPU-Z, I never realized you could measure droop this way. If there is a considerable droop - I should keep LLC ENABLED, right? Is there a measure of what should be considered a considerable droop?
Optimal is none, but to say .08 or .03 use it or not...I cant say. Its up to you, I would leave it enabled personally.
I'll try both ways and see where I'm getting at with stability.
Thanks!

The guys in this forum are giving you better advise than I could, because the memory 5:6 divider value came from AUTO BIOS settings except for the vDRAM which is set to 2.1v. I had tried the recommended 1066Mhz settings from the Corsair memory forum but they would not post with a "DET DRAM" message when I started to OC. The recommended settings were no problem on stock settings. In fact my first successes with OCing was when I returned my memory settings back to AUTO except for the vDRAM. I will admit that I could try tweaking my memory settings but unless the benchmark testing shows issues I will leave them alone.
I have started my next stability test with a slightly higher vNB. I will see if these settings are the stable ones.
Instability! Can't get past it.
I used some of the advice I got from you guys last evening and I was able to push the FSB up a bit. Right now I'm sitting @ 3664Mhz (458 x 8). The thing is, it's still not 24hr Prime95 stable - what's happening is that at least 1 core gives me "worker thread stopped" while the others continue without failing. One of the 4 cores always gives me (and they rotate) "worker thread stopped".
Also, I attempted a video encode and early on got the BSOD (which is a first for me during an overclock attempt) and I'm assuming that's from a failed overclock.
This is where my settings are at right now:
(I've bold the ones I upped/changed last evening)

NB Voltage: 1.30v
NB GTL Reference: AUTO

Right now all I'm looking for is 24hr Prime stable @ 458 - 460 FSB .. nothing more then that! But I'm just wondering if there's any more room up there, any more settings up there I can fiddle with that can help me.
Any advice?
Thanks guys!!

I would seriously try to work out your GTL settings. Taking them off Auto and setting them manually can make all the difference.
Start at 0.62x and work your way up to about 0.72x. You'll also likely find that both won't be the exact same setting.
Here is all the BIOS settings I had for the stable 463FSB:

I do not remember you mentioning is whether or not you applied the Pencil Vdroop mod. Here is a post where I think your mobo (P5Q Deluxe) was mentioned being moded: http://www.ocforums.com/showthread.php?t=557776
If you can I definitely recommend the mod with a 3B pencil.
I hope this helps.
Cob ... Agreed 100%. In fact, I'm going to be taking quite a few things Off of AUTO and start playing with actual values - GTL's being the first. Quite a few successful Q9450 OC'ers are using these settings - that's one difference I realized.
Actually I haven't applied the Pencil Vdroop Mod yet - I don't know anyone using a P5Q Deluxe who has, and I really didn't know if you need to or not. Actually I'll make a post in the P5Q Deluxe and see if anyone knows anything about this.Quote:

Couple of Questions regarding your BIOS settings:
Doesn't AUTO on CPU PLL take it too high .. towards unsafe limits? I haven't tried it on AUTO yet because I wasn't sure you could.
Same with NB ... I'm not sure what's the max supported for your board but I was told for the P5Q not to take it over 1.4
Only other thing is, you have CPU TM Function ENABLED .. does that help towards stability at all?
Other then that your settings look worth a shot - I'll give it one!
Thanks guys!!

Q9450 @3.2GHz 1.264V with a lapped TRUE+Scythe SFF21F(1600rpm)+AS5 on it.
Why is there a so big difference between the cores? I checked the cpu and its absolutely straight. Also i did the washer mod on the TRUE and it doesnt move one mm now. Is the mobo temp sensing wrong? Those temps are at idle but with a rather high ambient temp, around 30C or more.
A difference is normal.
Currently running Prime95 Blend atm and my temps are 51 56 57 49 (that's under water ofcourse).
LUCI5R your questions were:
1) "I couldn't spot anything pertaining to a P5Q"
> Here is a better reference: http://www.xtremesystems.org/forums/...age=4&t=111156
> See the user "jVIDIA" signature (post#80) it quotes a P5Q Deluxe and he said "I did the pencil vDroop mod and the results @full load are : before : 0.07 vdroop now : 0,005 ~0.01 vdroop".
2) Doesn't AUTO on CPU PLL take it too high .. towards unsafe limits?
> You are correct I have changed the setting to 1.51v but that ends up as a real 1.648v the same as if the setting was left on auto. I did a number of tests at lower vPLL but all failed. As mentioned before this is the voltage I am most concerned about.
3) Same with NB ... I'm not sure what's the max supported for your board but I was told for the P5Q not to take it over 1.4
> In my research the OC guidelines I have for the NB are "Not past 2.0v (<1.75 and lower)". It was very difficult to find widely accepted 24/7 guidelines for the vNB. My Rampage Formula has on board LED indicators with three colors (Green, Yellow and Red). As you can imagine Green is for safe and Yellow if for High while red is "Crazy". I am on the lower end of Yellow (1.51~1.73) with my vNB being a real 1.54v so I am assuming this is high but safe. My temps under prime95 load are at or under 50C. I have also seen a number of quotes of people running in the 1.50-1.55v range when OCing. Right now I am going with what the mobo and forums are telling me.
An additional comment on the high vPLL, I found an article (http://www.xtremesystems.org/forums/...d.php?t=179580) and it has an information table which shows a number of voltage readings (see: Bios to Actual vDroop listing). They show BIOS settings, BIOS Thermal Monitor values. their own multimeter readings and multimeter readings under load. These are all for the Maximus Formula mobo which is the sister mobo to my Rampage Formula. With the only difference being Maximus having an X38 rather than the Rampage X48 chip. I used the table information to extrapolate what my vPLL "multimeter" readings under load would be (three different ways) and they came out to be in the range of 1.580v to 1.599v.
This puts me on the knifes edge of being over the guidelines. I am not sure if I am deluding myself because I want to run at 3.7Ghz 24/7 or this is just good research. Of course the counter argument if Intel's own recommendations of max 1.575v then what the heck am I thinking?
I will make my mind up on how much risk I will take for a 0.1Ghz improvement after I finished tuning and stability testing.
Hope you have some luck obtaining your targets.
rdv, thanks for your detailed responses! Always helps.
That post is actually from 2006, and jVidia had the P5B back then. He has a P5Q Deluxe now which is why his signature shows P5Q Deluxe. (Signatures on this forum are backward-post compatible). I don't believe he was referring to doing to the pencil mod on the P5Q Deluxe. I've searched extensively in the P5Q Deluxe thread as well and found one other person (besides me) asking the same question - but no answers. I'll keep looking.
Makes sense. With the other massive changes I'll be making to the BIOS today, for now I'll restrain the vPLL between 1.54v ~ 1.58v
I quite agree with you - I don't think there is a widely accepted or standardized guideline of the vNB. Being on air - I think I'm being a bit more conservative. I think Cob and some others on Water are up much higher then I'm at.
That article was definately an interesting read.
Quite honestly, there's always a thin line between 'really good research' and 'self delusion in order to achieve goals'.
For now I have enough settings to fiddle with, so I'll probably be going through some trial & error myself on my setup - but I'll keep reporting here cause I get real good feedback & advice from you guys.
Thanks!
