CPU Overclocking: Limiting Factors?

[Gophermofur]

Hey guys,

I only ask this question becuase I can't seem to overclock my venice higher than 2.6. Well, currently I am running stock cooling and am running my AMD Venice 3000+ Cpu with 1.55 volts at 2.6 ghz. I can't seem to get any higher, or i'll error out in p95, even with higher voltage I can't push it further. My temperatures, even on stock cooling, are about 52 degrees at full load.

So, assuming temperature is the only limiting factor, my cpu (theorhetically) should be able to go higher, until the temperature is just too much for the CPU to bare. However, 50 seems sort of low, so I can only assume that there are other limiting factors. Is this the cap of my chip? (week 17 revision of the 3000) or would better cooling actually help me clock higher?

I will be getting better cooling anyways, I'm just curious if that would alos help me overclock a bit more. Any thoughts?

It could also be that you didn't get one from a good batch. Not all CPU's are created equal...

But you may have a point. With better cooling, you might be able to get a better OC. 🙂

up the fsb till u max out your ram and fail memtest. Then u know the point where the ram is limiting you and go from there. Im at 2.65 and not even hittin 50c and its very likely my cpu holding me back. But how can you complain about almost a 40-50% overclock.

2.6GHz is above average for that CPU. Why SHOULD the CPU run at higher speed when it was designed for 1.8GHz?

My CBBID Winny won't even do 2.4 🙁.

Mine does 2.46 so far 24/7 prime stable. That's what I have it on now. I think I'll try to molest it a little more this upcoming weekend before the FX-53 goes in 🙂.

Well, I can load Windows @ 2.53, but it will fail prime pretty fast, so I keep her @ 2.35 most of the time. Should have waited for Venice...oh well...that's still 500 mhz for ¨free¨ 🙂.

heh, sorry guys, I didn't mean to sound greedy that I'm not getting the extra 50 or 100 mhz, I was just wondering about the dynamics of limitations on CPU's. Thanks for the replies 🙂

1) Heat
2) power
3) mobo chipset ability to handle a high HTT or have necessary working locks
4) bios compatability with your hardware
5) Other hardware
6) too aggressive of ram timings for ram
7) incompatability of ram to mobo
8) faulty ram (it happens)
9) software issues....

Have you tried to up the LDT voltage and the chipset voltage? I was stuck at 2.358 with an LBBID until I upped the LDT voltage to 1.4v and the chipset to 1.7, now I jumped to 2.600 and still working on it,.....

Nice, I guess I could try that. Actually, I am a little bit scared of running the chipset at 1.7v, since right now it's on stock v, and it's already around 45 @ idle. Anyway, thanks.

I was stuck at 2.6ghz with my 3200+ venice....i will try upping the voltage for ldt and chipset

I can't get any higher than 2.6 myself, but i am not unhappy.

600 MHz increase is fine with me 🙂

I likely could get a bit higher if i cranked up the voltages for stuff, but i'd like this system to last for a while...

i can't get higher than 2.6 as well, it can boot into windows and you can surf but it will freeze in any intensive task, i dislike how the chipset is at 50 when you bump up the voltages
