yup and the slower the heat is removed from the heat source. physics 101 guys!

So I just finished adding the hd4870 waterblock and a second radiator (another 240) to my silent watercooling ..... the flow sucks of course, but this watercooling is able to remove heat from the ATI very quickly. 55º Full load using ati tool.

I still think this cpu is not right. Tomorrow i'll know for sure

....i can't belive that...that are temp for watercooling...and a good WC...

...i think it's possible...my old E8400 at 4120mhz got @ 38~39 degres idle and 49-50degres full...anyway...it's not a bad chip at all...the Vcore it's not the problem...look at me...i cannot reach 4.2GHZ like u because the temps go crazy...i got the same Cooler like u, and i run 8x / 470 FSB = 4GHZ @ 49 degres idle low RPM / 64 degres full high RPM /....and now i cry because i sell my old E8400...

Actually I set 1.53 in BIOS and not sure if vcore on CPU-Z or OCCT is right. Once again it's an OEM chip so I think it requires higher voltage than the retail one. My VID is 1.225 and I've seen other people have it at 4.0Ghz for around 1.3 or less while mine needs more than 1.4V to get it stable. And to get to the 4.2 mark I need like 0.1 more. But what surprise me is the temp is quiet good, as you can see I'm at 34 idle and 65-70 full load (44 idle and 75-80 full load in OCCT). I haven't tried to hit 4.4 or 4.5 yet but I think I should be happy with my chip for now.

What your temp like at 4.2Ghz?

Have'n fun with my new 8500 and gett'n back into overclocking after a year or so break, initial prodding looks okay. Not claiming its stable here, just use'n orthos as a load atm. Tomarrow if it pass's here i'll play with the memory and see how far i can go on 1.35vcore(my self imposed 24/7 limit), and to think i thought i was happy with my 3.6ghz e6600

Just got a new E8500. Batch Q817A328

Not seen any Q817 chips yet so I'll post up how it clocks

**Vivi** · 08-08-2008, 08:43 AM

i had a Q818. it sucked.. :/ well, by suck i mea 1.28 for 4ghz

**Zeus** · 08-08-2008, 10:48 AM

1.28V for 4GHz and it sucked? Hmmm, can you say spoiled?

**kpo6969** · 08-08-2008, 11:04 AM

Maybe it's your psu that sucks?

So far stable at 4.275ghz 1.44v...fails 4.3ghz orthos with 1.45v and thats the highest i want to go 24/7 on watercooling...

Clocks about exactly the same as my other E8500 :/ vid 1.225

**Kartoff** · 08-08-2008, 03:42 PM

Here is my latest result

Never even think about this CPU can do this :

I tell about this that CPU cant do more than 3650 MHz stable, but finally now i am happy with it, even it's not stable, but i can just write this post here

ok well i've been trying to make an automatic database...Just trying this out, we'll see how it goes.

Please fill out all fields. This is only for Wolfdale processors...

good jop gurusan

**zlojack** · 08-09-2008, 06:32 AM

Sweet! Nice work gurusan.

**gurusan** · 08-09-2008, 06:33 AM

yeah i think i will start a new thread and keep the 1st post updated.

**zfactor** · 08-09-2008, 06:34 AM

^^ i have a q817 and im at 4.2 with only 1.328v stable with orthos and prime

**gurusan** · 08-09-2008, 06:38 AM

cool, submit it in the database.

**roger_h99.nor** · 08-09-2008, 07:41 AM

Nice work gurusan.

Plz submit your E3110 - or update your signature - whatever fits!

**gurusan** · 08-09-2008, 07:42 AM

k will do.

Also here's the new thread

**mskvorc1** · 08-09-2008, 07:52 AM

Hm, interesting results in Wolfdale OC database. Are all of you guys running your E8400/E8500 over 1.4V (as you posted) for 24/7 since you posted they are Prime/Orthos/OCCT stable?

**gurusan** · 08-09-2008, 07:55 AM

I'm running mine 1.44v 24/7....I honestly dont see it being in any danger of being damaged, also temps are very low...especially during normal usage. During gaming and such temps range between 35-40c

Mine can go 4,037 GHz at 1.376V. Under Prime maximum temps are 64-65 C, but while gaming they are 45-47 C max, under idle around 39-40 C, so i should go for 4,037 GHz with no fear of degrading my CPU? I didn't so far wanted to go higher for 24/7 over 1.304V because of Intel's information about max voltage of 1.3625V...

**gurusan** · 08-09-2008, 08:15 AM

well if I were you I would definitely push it more....

I want to. It tickles me all the time, but since I spent almost all my money, I'm afraid of degrading my CPU. Temperatures were never the problem for me.. It's almost like I'm looking for approval to do it...
