is this even stressing this 2.8c setup?

2.8c / pc3200 ocz -> 215FSB? i just want to run it @ 3.0GHz and the temps dont really change from stock speed and i am running stock voltages. is this stressing anything at all?
 
no stress.

with that nice memory, you can get that 2.8 to 3.2 (230fsb) easily on air and on default voltages. this would be the sweet spot.

depending on memory, most 2.8c are around 3.5 and 3.6 based on www.overclockers.com database.
 
thanks for the info, it seems if i go to 220FSB, it will not post, and the board i have is a i865pe based board, but it is nearly oem as there are no areas to change voltages for cpu or memory. should i try to set the memory at 5:4 to see if it is a memory voltage problem or a cpu voltage problem? or am i way off in my thinking?

i have a nforce2 ultra boad sitting here next to me with an old xp2000 in it, i have really contemplated getting a xpm and a decent hsf, putting my ocz ram in it and messing with it, since that board has all the adjustments for voltages in the bios.....

thanks for the info,
bob
 
If you start to mess with the AXP, you may not even need your OCZ ram to OC it. Most AXP motherboards don't go much over 215-220 if at all, so that's why it's important to have the mulitpliers available-why you want a mobile XP. Quite a bit of PC3200 will run 215+ with a voltage boost. Use CPU-Z to determine if you CPU is a Thoroughbred A, TB-B or a Palomino core. If it's not Thoroughbred B, (6-7-1 code I believe) then you're not gonna get a whole bunch out of it. If it's a "b" core, you could approach about 2.2 GHz maybe a hair more ymmv. The Mobile Bartons often see 2.5-2.6 on good air cooling. As far as your original post, you could get a different 865 board for around $50 (watch the forums here, newegg refurbished, and ebay) and reach for the stars with your woody.

thanks for the info, i don't think i would do another p4 board since, i bought this because it was supposed to be better at video encoding and at the time, i was doing quite a bit of video creation/encoding. a friend of mine has a stock xp2800 and to be honest, and not to start a flaming war, but the xp2800 seems faster than my 2.8c with normal tasks, i am pretty sure my 2.8c beats the xp2800 in encoding but i am not doing that any more. but, then again i investe ~$60 in a nice big copper hs with a 92mm fan on it.... decisions, decisions...thanks for the info.

do you think if i were to set the ram at 5:4 and increase the fsb as high as i could ~225 if possible (if it is indeed the ram voltage that doesn't let me go to 220 and not the cpu), the cpu speed would be a better benefit than leaving the ram a 1:1 @ 215?
 
Set the CPU:memory to 5:4 (or even 3:2). Then see how high you can go with FSB. That would be the limit of the CPU at the current VCore.
Always make small changes and test after each change.

thanks, i am going to put it all back to stock and run prime95 tortue test for a couple of hours (the one that stresses the cpu, don't care about the ram since it will be running slower than it is rated) so i can get a baseline for the temps. i just cleaned it out with compressed air so all should be good to go.

idle temps are 34C cpu / 26C case with a room temp of 22C.

thanks for the info.

looks like after running prime95 since my last post, it plateau's out at full load - 52C cpu / 28C case and still 22C room temp....

i will cut the memory to 5:4 and push it the chip to 220FSB and see what the temps are ( i know this is a safe o/c as i have done it before )
 
My 2.8c is running at 266 fsb (3726) at about 51c, which is hardly stressful for any cpu. I've let it rise to 78 celcius, but it didn't effect stability much. These northwoods are pretty tough, as long as you keep the voltage below 1.7.

thanks for the info, since my board won't let me change the voltage it is sitting at 1.440V, according to cpu-z
 
looks like ~ 3 hours of prime95 torture test and the readings are as follows with 220 FSB - 56C cpu / 29C case and room temp of 23C, now will go to 225FSB....
 
225FSB - prime95 gives me a hardware error, but temps were 53C cpu / 28C case and 23C room and voltage is still 1.440V when i got the error. is this where additional voltage would help out? is there anything in the bios besides a voltage change that can help? what exactly is spread spectrum?

backed it down to 223FSB, will see.
 
So, this was done after you set the CPU:RAM to 5:4?

Spread spectrum modulates (fluctuates) the clock frequency in order to reduce electromagnetic interference that the CPU clock may cause for wireless equipment. It has a minor negative impact on overclocking. If you want, you can disable it.

Yes, if you had control over VCore, it might help.

You can increase the overclock by improving the CPU cooling also.

What is this motherboard that does not allow the VCore to be adjusted?

223FSB does the same thing with the error and i can't get a post at that speed with the ram @ 1:1. looks like 220FSB for now.

the motherboard is this unit

the temp doesn't bother me @56C, i just want to keep it under 60C. plus it will only hit those temps when gaming or encoding, idle speed is 36C cpu and case is 26-27C with room of 22-23C
 
Did you run the test at 5:4?

When you run prime95, it loads the CPU and it heats up. If you cool it down, you can overclock more and still be stable.

i was just letting prime 95 run continuously, but i think it ran for about 20mins before error and again the temp was not high, that is why i am wondering if it is a voltage issue.

hows my 50% overclock stressing it? :evil:

TT venus with AS5

not bad, i am running a large coolermast copper with those heattubes with a 92mm fan attached that is turning at ~3000rpm with AS5 🙂
 
223FSB runs prime95 for over 4 hours..., so that is where i will leave it until i get (if i do) another board.
 
i am assuming it is locked because the hardware utility that comes with the board shows fsb @ 223, cpu @ 3122, pci @ 33 and agp @ 528
