Nice

I have a 3.6es 775 sitting here waiting on a mb. Can't wait to try the new cpu and pci-e video card

sweet o/c man!

If that's on air, you can't do that with a Prescott. They're way too hot. Their extreme heat forces people to use water blocks or other exotic cooling just to run them at idle.

Not funny. quiet!

rofl!

now if you were to liquid cool a preshott, would you get boiling water?

I'm running mine at 4.0ghz without issue... I haven't tried any higher yet.

On air? Say it isn't so...can you boil Ramen with your cooling system?

It's idling at 46C right now, and hits ~60C under load. This is with the cheapest ($21) heatsink I could find... Link. Oh yeah, I'm running a Lite-On 250w power supply, too.

 

[Sc4freak]

I've currently got my 3.4ghz Prescott running at 4.0 ghz, too. On STOCK cooling . Running 45C-50C idle and 68C-75C load.

I still love how my 99 dollar chip outruns these

 

[kumo]

OMG i don't get it... my 3.4ghz prescott runs at 60 degrees idle and 79 degrees under full load WTF!!!!!! and you guys all told me that was normal... i have stock cooling nothing is overclocked at all... i'm sure everything is installed correctly and am using silver thermal paste this just isn't fair.... is it all a possibilty that it's something with my cpu or does it have to be something with cooling?

You should update your knowledge. That's about the old Prescott. Newer steppings (D0) fixed a lot of heat issue (most of 775 Prescotts are D0, btw). Most people easily reach 3.6+ on air, while some people even reach 4.2+ on water. Also, remember that there are not many HSF for 775. As soon as the great HSF manufacture, Thermalright for example, introduces a great HSF like XP-120 for 775, you will see people get 4.0+ OC with them easily.

It probably should be noted that LTC8K6 was being sarcastic.

Yeah, the other day I had to throw a bucket of water on my Prescott to stop it from smoking. Good thing I had a bucket of deionized water handy! :laugh:

How Are you able to increase the FSB and still have the 17x multiplier? I thought you had to enable the lock free feature which decreases the multiplier to 14x in order to increase the FSB.

 

[Sc4freak]

Thats not exactly true. Most motherboards with the new Intel chipsets have a 10% FSB overclock limit. ASUS have not only broken this, they have also implemented a "CPU Lock Free" feature to lower the multiplier to 14x in order to raise the FSB even further. I myself have my 3.4E running at 4.0ghz, using a 235FSB on a 17x multiplier.

Now that I have my new Thermalright XP-120, it idles around 40-45C and at load it around 60C

 

[bfull1478]

My rig idles at 35c and 49-54 loaded. I have a stock intel fan.
Their is something to say about lan li cases. I have 2 intake fans and 2 outake fans. If I turn off the intake fans it runs about 5c's higher. I also have other antec cases and the processor runs 10c's higher. I chose the overclocking profle of ddr 600 and fsb 900. Seems to be stable.

I'm running a P4 530 on an ASUS P5GDC Deluxe motherboard cooling with a Zalman CNPS7700-Cu. My temps rock, idling around 39-40. Hitting mid-50's under load (by load, I mean running Prime and SuperPi simultaneously). Also of note is that I'm in a stock Antec Super Lanboy case (aluminum with 120's in and out) and I'm running a super clean Antec Neopower 480W dual rail PSU.

My 3.0 gets to 3.7 stable at default voltage (memory is DDR1 Corsair PC4400, btw). If I go one bit past whatever my current bus speed (245), the system just will not POST. It seems strange to me that the system will run like a top at ~3.7 but won't budge another inch.. with cpu temps this low. The bios says it locks down everything else. Does this mean the 915P chipset on my motherboard is my bottleneck? Has anyone cranked the chipset voltage or changed the cooling? I've heard Intel has some sort of 25% lock, but I'm just now starting to read on this (D0 stepping).

I thought ASUS was supposed to have defeated that 10-25% lock issue, but it appears to still be around. I see people with the 3.4 hitting 4.0-4.1 (120%). My buddy got his 3.6 to 4.5 (125%). My 3.0@3.7 is 123%. Is it a limitation of the cpu? The chipset? What gives? Changing the voltage on the cpu does nothing to my ability to OC. My temps are well within range on the cpu. I'm not throttling at all (throttlewatch).

Any advice? I don't really need any more speed.. but I guess that's true to everyone here.

 

[bfull1478]

I have the p5gd2 deluxe, I am pretty sure they got rid of that bottleneck on this board but I am not sure about the p5gdc. I will look into your issue.

Very nice..Well done.

I just snagged the 1007 beta 2 bios from the german ftp site for asus, and I seem to be able to pass the 245fsb point now. I'm running 250fsb (ddr500 with the corsair 4400). I think my memory settings are the issue. I've heard the asus bios doesn't do SPD correctly at high speeds, so it is imperative that they be set manually. I'm in the middle of moving some files around on my network tonight via ftp, so I can't play too much, but I'll work on the memory timings this weekend to see if I can get more. My memory is supposedly tested at default SPD settings 3-4-4-8 to go DDR550 on 2.8V. I can push 2.9 to it if needed with this board, so I can't imagine once I set the latencies that it will hold me back any longer. I really want to get my cpu to 4.0ghz (only 200+ mhz away!).

FYI, asus probe says my cpu is running 42C Idle on a a 33C mobo. I'll report load numbers after I finish ftping the files.

I can run my p4 @3715Mhz , Intel Box-cooler 60 degrees idle in a 39? case without casefan
fsb: 888 mem: 776

Strange things i run into are:

- overclocking with AI NOS system result in high memory latencies,
no matter if u set it manual, the AI system ignores this.
- Hyperpath lowers latency of memory, resulting in fried memchips when oc'íng manual
- when i put it on DDR600 in bios it still seen in windows as DDR2-400
- Corsair SPD totally ignored by mobo, maybe coz it has only 333mhz timing in spd-table
- memory of videocard rated @900Mhz Hynix 2.2ns, can't get it higher. overclock-utility's maximum
