VID in a Dell?

[RobMonty1987]

I have a Dimension 9200 E6600 (2.4ghz) overclocked to 2.8. I would like to his 3.2. Temperature is not an issue. However, its startup and maximum voltage are 1.35v. I cannot find a way to read the current voltage. I've tried so many programs -_- Has anyone had any luck reading voltage on a Dell or in a locked bios whatsoever? Also, what kind of risk am I taking by overclocking blind to the voltage like this? Anything I can't recover from? Thanks.

DL a program called CPUz and that will tell you.

Why did you start another thread in the PSU section? Your original thread would have been fine.

The program I linked to "CPU-Z" Should tell you the correct Vcore that your chip is currently running at.

It may change very slighty according to system load, but it is impossible to increase the Vcore on your system due to the locked BIOS

Just so you know:

The VID is the voltage that the CPU manufacturer (Intel in your case) has set to ensure the CPU runs 100% stable at the stock speed.

[RobMonty1987]

Sorry, haha. I was actually about to post in the original thread saying thanks and restating my question here because I felt the topic changed and just wanted to abide by the rules ><

I have CPU-Z, but the core VID does not change from 1.35v. It reads that before I start, and after I reach 2.8 without change. So where can I read current voltage in CPU-Z? Thanks... I've never had to worry about voltage before.

[jmdixon85]

No problem. This thread belongs in the CPU>Intel forum though...no biggy though. Thats what mods are for.

As I have said in a system such as yours the Vcore isn't expected to change. It looks lie 2.8Ghz is you limit I'm afraid.

[RobMonty1987]

Ok, well let me clarify about something. I haven't tried to go any higher than 2.8 yet. I ran P95 for 12 hours with no problems. I'm curious why you say I've hit my limit. I didn't mean to imply that I am having problems going past 2.8, but is there something you see specifically with my setup that would limit me to that speed? Also, what are the risks (and likelihood) of increasing the FSB further without knowing the voltage?

[jmdixon85]

It was your first post in your original thread that made me think that. You said your research turned up that many users couldn't go over 2.8Ghz (or something similar) on the same system.

Most risks when overclocking are from increasing the Vcore. Since you can't do that your system will simply freeze or fail to boot/post if you push it to far. There is virtually no chance that you could do any damage to the CPU.

[RobMonty1987]

Crashing is the only thing I have to watch out for if my temps are ok? That is what I wanted to hear, cool. Well, dixon, you have been incredibly helpful. I guess I will now attempt 3.2, assuming my temps stay low. Any final recommendations?

[jmdixon85]

Just keep an eye on those temps my friend. But at stock Vcore even that shouldn't be a worry.

I would say try keep it under 60c at full load (prime95) 70c absolute tops! Good luck :thup:

[RobMonty1987]

Thanks a ton, you've been very helpful.

[jmdixon85]

No problem :) Don't forget the thank you button at the bottom of my posts :p

Let us know how it goes :thup:

[EarthDog]

GAH, this is the problem with double posting.. no clue wth is going on in that other thread.

If you cant/dont change your voltage it wont change in CPUz. CPUz is dynamic with voltage changes.

Amen to that :thup:

But hes new and I think hes learning :)

Hell, cant say I'm supprised with some of the other computer related sites and there lack of moderating.

He will soon get used to this being his 2nd home :thup:

[RobMonty1987]

Sorry for switching threads guys ><

Anyway, here are the fruits of labor so far:

Gonna sit here for a while and stress test. So far idle I am at 23c and max load about 45c. Oh and yes, I am new to overclocking. Sorry for all the questions, I'm sure you get worse. If its any consolation, I did do a great amount of research on the topic for weeks before I asked any questions or even thought of trying anything. Thrilled that I'm successful. This machine was my first to practice on before I build a new rig, but I think I might just keep it for side projects now since it isn't half bad anymore :thup:

Thanks alot for your help

[jmdixon85]

Well done :thup:

Thats a decent overclock considering you are stuck at stock volts.

Run Prime95 for an hour or two and push onwards if all is good :) I wouldn't expect to much more at stock volts though.

[RobMonty1987]

Thanks! All seems well with it. One more question and I'll be done, I promise :D

Is there any possibility I could use this pin-mod (http://starless.nl/pinmod.html) along with my current overclock (w/ ClockGen) to go even faster? Or would that produce the same results as what I am doing now? Or should they just not be used together?

I am shooting for the stars here, right down to the Arctic Silver.

[EarthDog]

You are going to be voltage limited so using that application wont help as you are not limited by FSB or what your bios can do.

The Song Remains the Same.

[RobMonty1987]

Wait... I thought the whole reason my voltage was not able to be increased was because my bios is locked and I am limited by what it can do? Not to be contradictory, just trying to understand... This page here (http://www.tipidpc.com/viewtopic.php?tid=98439&page=1) also states the reason for the mod is if you cannot adjust the voltage. Thanks

Nope. Never heard of that pin-mod.

But even if it works it still doesn't increase your Vcore. And thats needed at 3ghz+

I would call it a day and be very happy with the overclock you have :thup:

Sorry but I've never heard or seen of this done. So I cant comment.

[EarthDog]

I thought the pin mod was for default FSB (i did not look, just assumed), not voltage. So yes, that would help if it works.

[RobMonty1987]

Well from what I'm reading, there are 2 different kinds: One for FSB (BSEL mod) and one for voltage (VID mod). Here is a link (http://www.overclock.net/intel-cpus/341123-intel-bsel-vid-mod-guide.html) that I think explains it thoroughly (scroll down to VID mod). I'm debating on trying this, since it appears it can bump me up from 1.35 to 1.45v and maybe squeeze in some more speed. But like I said, I'm new to this stuff, so I'd like a 2nd (and 3rd and 4th) opinion :D

Mainly I'd like to know if I can cause any real damage with .1 more volts to the CPU. I read about volt mods on here so I think I should be safe, but still, input always is appreciated.

[Evilsizer]

vid pad mods are possible but you need the VID of the cpu. always found in coretemp and realtemp, cpuz will display realtime voltage. there are rare instances where i have seen it posted that it shows the VID of the cpu.

knowing the vid is the first step then looking up the settings for that vid, then figuring out what to change the settings too. without seeing the motherboard it is hard to say how much you will want to push the cpu. since dell has the boards designed to operate at a set max TDP. assuming the board can take a quad core then ocing the the dual core with vid pad mods wont be much of a issue. though i still go back to seeing the board is a biggie for me, i dont like seeing ocing on boards with a low count of pwms for the cpu power section. as this will cause problems down the road, as pushing the PWM section section beyond or near its limit will generate alot of heat. generally when the cpu pwm section is pushed to far it could result in programs crashing or windows/system not booting up.

i think as long as you dont go over 1.35v, then you should be ok. i dont think the board would be able to handle much higher with a oc on the cpu as well.

[RobMonty1987]

Ok thanks for the info. Did some reading and saw that many people run at 1.6v with the E6600 and most advise 1.55v as the maximum safe-zone. In CPU-Z it shows my maximum & current VCore at 1.35v (I assume because the vcore is at a fixed rate? do[/U] have EIST and C1E disabled]). Is this an accurate reading? Now naturally I'd like to find out what my board can stand as far as voltage. I read this straight from the TDP wiki:
[I]
"The TDP is typically not the most power the chip could ever draw, such as by a power virus, but rather the maximum power that it would draw when running "real applications". This ensures the computer will be able to handle essentially all applications without exceeding its thermal envelope, or requiring a cooling system for the maximum theoretical power (which would cost more but in favor of extra headroom for processing power)."

...and I do know that the board I have (Dell DXP061) can support quad-core cpus. Do you think by +.1v I am jeopardizing the TDP enough to risk a failure? I guess going by what you are saying I should be ok, but I do still heed your warning. With all of that said, how much more speed do you think I could get from an extra .1v to the cpu? A ballpark estimate is totally acceptable. Thanks again

[EarthDog]

No... try it.

[95blackz26]

i did the 1333 fsb mod on my e6600 that i put in an optiplex 330. easy free overclock for 5 minutes work.

you can also do the same thing with the default voltage as you do with the fsb

http://www.overclock.net/intel-cpus/341123-intel-bsel-vid-mod-guide.html

[Evilsizer]

well not all cpus will respond the same way with voltage increase. that makes it harder to say if .1v is going to be enough. i would almost say this could be the best pad mod post but being i didnt have it all straight for L and H signals you want to read the post after mine or was it a few down. my post lists every Bsel signal intel uses for LGA775 cpus so you could take it to 1600fsb.

complete LGA775 and core 2 based mobile bsel table (http://www.overclockers.com/forums/showpost.php?p=5804035&postcount=17) as you can see the mobile side never got the rest from the tables i pulled from. seeing as both lga775 and the mobiles have the rest of the same signaling you could use the same on the mobiles as well if you wanted to try.

really about the dell board, a picture of the board would be helpful. more specifically a picture of around the cpu socket and the surrounding area.
