Vista - Post Your Overclock Results.

ya thats no good. For a while there I was thinkin maybe my RAM is holding me back. I was trying to use a weird divider and I couldn't get above 3.66 GHz. but now if I go to a 9x multi. and get the FSB higher, then the 1:1 in Sny'd mode is very easy to acheive. and thats in the end. a more stable, and said to be a better OC. so thats what I did. and sure enough it worked.

Here are my new results for the E8500 I just got today.

Now I just need a better graphics card, hmm...

A GTX280 would be nice or two!

Was 1.4 volts something you just entered, or did you find you had to go that high to stay stable? That's a lot for a Wolfdale doing 4GHz. I would hate to see your chip suffer an early death.

I have read that 1.45v is the maximum safe voltage, but the only reason I have it at 4v is because Orthos would fail after a couple of minutes any lower than that. Other than that everything else seemed fine at a lot lower voltage, also when using Orthos voltage drops to 1.35v is this normal?

And the other thing I am worried about are my temps they are a bit high under stress, got to 70-80 and about 40 while idle, need some serious cooling if I want maintain some good clocks with this one!

uhh... ya you need to NOT do that, those e8500's are great chips. and they OC like mad. but question. are you on stock cooling. Sounds like it. Many people can get those chips to 4 GHz and above on air cooling. but not stock cooling. you need to invest in a good cooler if your going to clock that high.

I'd recommend the TuniqTower, I have one. works great. or the TRUE.
thermalright ultimate extreme. it's supposed to be the best. what do you use?

Also 1.45v -1.5 is ok for the 65nm chips. but I believe it's a little lower for your chip. your chips voltage recommended Max voltage is 1.3625 so I'd recommend staying in that area. and yes when you run orthos it should drop so it running 1.35 at full load is normal. when I run 3.7 GHz on my Quad in BIOS i set it for 1.4812, but when full load it shows up as 1.448

You need better cooling. as the CPU should never go above 70c. most people say an overclock is only considered stable if it stays under 65c at full load. so I'd tone that down a bit until you get a better cooler. and try not running so many volts.

Thanks for the advice, I was using stock cooler but I went out today after work and got the best one I could find in this area. I bought the ASUS Silent Knight II and running Orthos again the temp is back down to 60c and I think that is fairly safe. I was reading on the overkill forum that 4.5v is the maximum safe voltage to run on the 45nm chips, are you sure it is 1.3625v? By the way I was going to get the Thermalright Ultra-120 eXtreme but nobody had one.

If nobody has the True, you can always opt for the 120+ or the Ultima-90. Surprisingly, the Ultima-90 performs incredibly well: AnandTech: Thermalright Ultima-90: Small Wonder? Those 2 additional heatpipes seem to really make a difference.

1.45 volts is too much for a 45nm core. What you read are, at best, optimistic estimates based on the fact that 1.45 hasn't immediately fried a chip yet, for most people. It's still too soon to say whether or not these cores can handle it. I'd stay under 1.4, and never attempt it with stock cooling.

ya you'll be ok with that cooler probably. if your able to stay around 50C at MAX during load, then your ok. no more though. maybe 63C at most.

and the TRUE is the Thermalright Ultimate Extreme. they have a normal one called the Thermalright Ultra 120, and the extreme is the TRUE hense the E. it's better, like fumz said, if you can get the 90, or the 120. I'd strongly recommend it. or get it shipped. I know plenty of AU peeps that have them. I use a Australian Forum also.

if you cant find that look for the Tuniq Tower.
Also give this a look for the complete correct Thermal design limits and voltage limits for your CPU.
Filter Summary

Acording to this, the e8500 just like I said, max should be 1.3626. you could probably do 1.4v and be ok, but thats when you might be betting on the life of the CPU. but thats a small ammount over it, don't take my word for it. but it's the people going an entire click over the design limit like you said that are Gambling. I'd not go anywhere above 1.4 like my Q6700 can be up to 1.5v and the higest I've gone yet is 1.4812. I've yet to try 1.49, i think that could get me to 3.8

oh and on that same page i linked to. I found some really cool, and interesting info. Most intel CPU's Max temp limit is 70c, and above that they can be damaged and even have automatic shutdown for protection. but apparently these new 45nm chips can handle more. and thats really really cool. the e8500 with C0 stepping. (Whats ur stepping?) can handle a thermal
design power limit of 72.4 C. thats 2.4 higher than the 65nm chips. that makes a difference in OC's. and even better, the newer e8500 with the new and improved, and great overclocking E0 stepping has a better thermal rating of 74.1 C thats not to shabby, but either way. I'd not go above 65C just to be safe.

Thanks for the advice xguntherc, the cooler I have now seems alot better but could you tell me if the ASUS thermal paste is ok to use or would I be better off using one with silver in it, like Artic silver? I ask because I have some, not Artic silver it just has silver in it, but I read that it can be harmful if you aply it wrong, something about shorting out components.

Also whats the best way you know of apling it?

To answer your question my stepping is 6 and I would say that the temps dont go much over 50c under normal load, it only goes higher when I use Orthos for about 1 hour and the temps max at 60c at night and 65c during the day.

Also I know that my voltage is a bit high but if it stays cool and its stable, will the damage and threat to the life expectancy be fairly minimal?

Please let me know about the thermal paste as I am thinking of tring it out soon!

THanks in advance!!

not too serious oc (2.8 to 3.2). temp stays fairly consistent ~33 degrees C, gets up to 48 degrees C when encoding video. thermaltake silent 939 cooler. as far as that gpu-z shot, i don't know what's up with that! all i can say is that i just installed catalyst 8.9 on 9-20-08--maybe that's the cause (?)
