E5200 voltages?

The cache makes a pretty big difference; xbitlabs and some french site did a huge comparison of like 50 chips and that was the conclusion.

Yea I don't want to spend that kinda money on my 2nd rig (& as mentioned there is a huge price difference!), an o/ced E5200 will be ample , atm it's running a Sempron 3100 @2.5GHz, which TBH is fast enough for the games etc it runs.
I just happen to have a S775 mbrd & some DDR2 RAM kicking about so I thought I'd best put it to good use .

I've read reports where people have known the mbrd can do a much higher FSB, yet even with a low multi the E5200 still can't do the higher FSBs .

The foxconn was rated to do 400fsb, and likely would have with say my E8400....


If the chip has issues past 333fsb...so be it....At stock multi overall clock speed will likely limit you anyways....


hold 333fsb and adjust the multi.

The chip seems to have problems at 400fsb. I never even got it to boot at 400. Right now I'm running 333x11.5@1.36/1.38 with idle temps at 30*C and load at 59*C with a Thermaltake V1.

I'm thinking of backing it down to 3.33ghz(333x10) though. I'm not sure if there's degradation from running 1.36/1.38 all day.

Still I'm incredibly happy. Thats a 53% overclock from a $80 chip.

My E5200 seems to have hit a FSB limit at about 270MHz. A touch more voltage to the chipset got another 5MHz or so, but that's all. Running at 272 x 12.5 = 3400. . . which isn't bad for the money. Just a little frustrating that it's still running at less than 50c at full load (Real Temp), core volts are low (Prime95 testing now at 1.26), and the motherboard should run to 400FSB.

I take it you've tried higher vcore with no luck?

Still haven't got my E5200 yet, ebuyer still haven't dropped their prices yet!:roll:

what are your ram settings? divider" timings? vdimm?

How do you know that is an FSB limit? have you tried dropping the multi to say 11x and running 300fsb or 10x and running 333fsb?

I had the multiplier low and ram divider low, so the CPU was running at about stock speed and the ram under it's 800MHz rating - i.e. nothing else overclocked. I think it's a FSB wall because suddenly I go from being able to run a VCore of 1.26 at 266MHz to 1.35 and 275MHz won't post. Gave the northbridge more juice, gave the ram more juice, all nothing, a sudden stop to FSB increase.

I've actually had to tone back from 272 to 267, as 272 was intermittantly failing to POST. 267 ran Prime95 overnight with lots of voltages reduced and was happy.

Is it possible that there's a band of FSB speeds that won't work, but perhaps a higher value would?

I would try it.....

may want to jump right to 333....prehaps that is a new strap location....try 10x333 = 3.33ghz and then 10.5 = 3.5ghz.....

My E5200 post and ran at 3.5ghz using 10.5x333 as well as 12.5x280....

That was on a 49 dollar foxconn Nforce 610i mobo

Alas, I forgot, I can't get my FSB higher than 300 without overclocking my ram due to a crappy set of memory dividers (2.66 x FSB is the lowest) - and when I tried to overclock my ram earlier I had no success. Overclocking the ram is a whole new can of worms (that I intend to open in a day or two )

How would you feel running an E5200 idle at 1.392Vcore and at load at 1.36Vcore. 24/7? I can hold 3.83(333x11.5)ghz at those vcores but I'm not sure if it's safe/if theres any degredation. Temps are fine, 59/61*C load, 30*C idle, but I'm wary about the idle and I dont want to kill the processor.

On the other hand though 3.83ghz is a great speed.
