Casual OC e6300 on P5Q PRO

[fritzfield]

Background - casual OC since Celeron 300a @ stock 66mhz to 450mhz by raising FSB to 100 on ABIT BX-6 with stock cooling.

Able to get P4 Northwood 2.6 to 3.02 by just raising FSB with stock cooling.

I recently had an e6600 on a Foxconn P35A that would go from the stock 266 FSB to 323 FSB stable just by raising FSB in BIOS using stock cooling and stock voltages etc. I gave the cpu and mobo to my son in August and bought an e6300 on ebay and the P45 chipset P5QPRO from the 'egg.

Now, I can't get past a 274 FSB from the stock 266 FSB* using stock fan/heatsink trying to do the same type of "casual" OC method of raising FSB in BIOS. Temps start to go past 70C and OCCT flips out.

Any suggestions using this chip on this board with stock Intel HSF. As I said, I'm a casual OC'er trying to get some extra FSB out of my chip.

*I edited in the CORRECT FSB. MY BAD!!

I remember I couldn't even squeeze more than 2.8GHz out of my first E6300, but it was doable with the stock heatsink. The E6300's thermal threshold is 85°C so you can go in OCCT's options and change the max temp to 85 from 70. I thought the stock FSB was 266x7=1.86GHz on the E6300. Perhaps you're talking about 400 FSB?

The stock FSB on an E6300 is 266, not 200. Are you sure you don't have an E4300? Anyway, you shouldn't be hitting anywhere near 70C with such a small overclock. You must not have fully seated your heatsink, when you installed it.

The HSF assembly is correctly and stably seated/mounted. I guess that I should dis-assemble the unit and remove the AS paste that I applied and reapply again to see what happens. Again, sorry about the original post's incorrect stock FSB for the e6300. But the measly 8 megaherz gain is correct.

I'm sure that's because you aren't lowering your RAM's speed, like most noobs. Have you read the overclocking sticky, BTW?

Noob for sure. I did have the memory set lower than 800, 777 to be exact. What I hadn't realized was that as I manually raised the FSB I left the vcore at AUTO. I noticed that if I raised the FSB, the vcore jumped way up - up to 1.38 - when set to AUTO according to OCCT. I went back into BIOS and set it manually to 1.30. Now OCCT shows vcore at 1.28 (vdroop?), and the temps aren't going past 65C.

I am now at 310 FSB, stable and not over 65C. So, I guess that after 2 months I've finally figured out that on this P5Q PRO, leaving vcore at AUTO does not keep vcore at stock, but it actually AUTO raises the vcore too high, trying to anticipate the needed extra juice. However, this creates too much heat and lowering the vcore manually solves the problem. I think that 1.30 is higher than stock, but the temps are WNL and the OC is stable now.

Anyone have a stable stock cooling max FSB and vcore, for this e6300 CPU?

Thanks for your help.
