Do Intel boards 945 and 955 support overclocking?

Intel boards are less attractive when it comes to overclocking. I am actually planning to get myself Pentium D 820 initially running at stock speed. I saw someone overclock 820 to as much as 4GHz and 830 to 5GHz. If I oc my 820 to 3.5 GHz by next year and to 4 GHz by 2nd year, I will be able to live on the top edge without upgrading too much.

My question is - Do Intel boards 945/955 support CPU overclocking?

If it does not, Asus P5WD2 (955 chipset) should be my choice. Any suggestions??


 
Most newer Intel motherboard bios settings have a "Burn-In Mode" which is equivalent to a 4-5% overclock.
 
I have the P5WD2 paired with an 820 - I have it at 3.36 right now, with no problems at all on air. Esbach over at sharky got his 830 up to 4 somthing on air, and broke a world record with a 2 stage phase unit.

The Asus is a great board, and for the money, let me repeat that so that I don't get jumped on by the millions of AMD fanboys/girls out there, FOR THE MONEY, you can't beat the 820, IMHO. Only think I wish it had was ht, because I really like the idea of four threads, even if 2 are software....

 
Jakedeez, be glad it isn't HT. Currently Intel has a bug, where if you use two threads, it will only use one core and one virtual core, not two cores. That will significantly hurt performance. Hopefully, Craposoft will come to Intel's rescue and improve the task manager to recognize which cores are virtual and wich ones are real.

Also, the 3800+ is out! Woot!
 
The chipsets support overclocking, usually Intel motherboards don't support OCing, or very limited OCing.
 
Intel boards don't support overclocking with their very limited bios features, other than their "burn in mode" on some boards, but it could possibly be done with clockgen. I'd go with the Asus. Gonna have to get some crazy cooling for that thing, I had to water cool my 3.4ghz single core to keep it from throttling..I can't imagine having to cool 2 of those cores..

Good to know, thanks!

Also, I should say, I really would have gotten a x2 4400+ but it was just sooooo much money....
 
All non-intel chipsets support overclocking perfectally fine beyond the 5% level. Infact the i955XBX is a better peformer than the majority of major brands. To be honest I wouldnt expect 4ghz from a Pentium D. That will come later this year with the release of Presler.

If you are expecting 4ghz I would stick with a 6 series based chip. (like what I am using)

Very true. It had occured to me HT on dual core might hurt things. Second thread wouldn't know there is second core available to its disposal doing nothing and hence would take the first virtual core which is already entertaining 1st thread. Unless OS finds some way of differenciating Virtual Cores from Real Cores, load will not be distributed evenly. Craposoft branch of Intel or something?
 
Intel's board do support overclocking. Now the question is how much. From what I have heard:

Any Intel Desktop boards with 955X chipset supports up to 30% overclocking on the dual core Pentium EE, all other chips can only be overclocked to 5%. All other chipsets can be only overclocked 5% regardless of processor.

Intel desktop boards with 955X chipset supports overclocking for memory, processor, PCI-E voltage adjustment, RAM voltage adjustment, I don't know if they are only for Pentium EE though or other CPUs as well.

If any of you guys didn't know, DDR2 memory overclocked to 902MHz on the D955XBK!!!

http://www.legitreviews.com/article.php?aid=184&pid=8

"Legit Reviews will have more articles on dual core in the near future. Although we didn't talk about overclocking, it is going well and we have been playing quite a bit. On the memory side of things we have gotten up to DDR2-907MHz and are currently getting around 4GHz out of the processor. Just to tease you a bit, take a look at the multipliers on our sample (14-60), the new BIOS has overclocking options up to 30% as well as the voltage options. Has Intel really opened up to the idea of overclocking? Stay tuned as our next dual core article will be later this week, and will focus on overclocking these new chips."

Multiplier of 14 to 60x(for Pentium EE only, other CPUs are multiplier locked)
RAM voltage up to 2.08V
30% burn-in(for Pentium EE only, other CPUs 5%)
 
eshach over on sharky got his smithfield 830 to over 4GHz on air, and a bit over 5GHz (I think a world record) on a two stage phase change unit.

There is no software limit placed on overclocking on non-offical intel based boards. Perhaps this may be the case with the i955XBX but it surely is NOT on any other i955X based chipset.

3200 / 4150 = 23%.

I am already well above the 5% mark on a non-EE chip
 
My mistake, I meant all other Intel Desktop Boards that are not based on 955X can't be overclocked more than 5% regardless of processor.
 
The first review I read of the 955 reference board the reviewer was shocked that the bios had good O/C features . so i would say that the 955x does. don't know about the 945
 
Well, the 955 IS rated to be able to use FSB1066, so all boards using this chipset will reach that, at least.
