Overclocking E4600 on Abit IP35 Pro XE?

[Shaolin_K]

Hi

I know most people here are into the latest and greatest, but hoping for some advice on slightly older tech.

Anyone else clocked an E4600 (M0) on an IP35 Pro XE?

Am wondering what overclocks have been acheived and with what voltage settings. It seems mine is at 3.2ghz; vcore being 1.435. This seems a tad high to me. CPU VTT is 1.27 (from 1.20) and MCH is 1.31 (from 1.25).

With the FSB at 266, does the latter two voltage settings affect anything?

RAM is OCZ PC2-6400 ReaperX HPC, running at 2.1v at 5-5-5-15 at 1:2 ratio, resulting in 1066mhz.

I thought I could get 3.4 - 3.6 on this E4600 - maybe a little too optimistic?

Guys - I could really do with some help / suggestions here

After further messing about, I thought I was stable at these settings for the E4600:

Vcore 1.4350
CPU VTT 1.20
MCH 1.33

However, it can sometimes pass an hours' standard test in OCCT v3.1, but at other times, it could detect errors not even 10 minutes in.

Currently re-*running tests with RAM at 800mhz.

Make sure that the FSB to RAM frequency ratio is 2:1. Hence if the FSB is 1066MHZ the RAM should be running at 533MHZ. Oveclocking 800MHZ RAM to 1066MHZ may end up damaging it.

OTH, from my experience of overclocking an E4300 and E4500 achieving upto 3.2GHZ is not too hard and anything above that needs a lot of voltage.

This article on E4600 overclocking should prove useful to you:

I found that useful, thanks

Thanks for that CAT.

I'm aware of the article. I know not all processors are created equal, but seeing they've reached 3.3ghz with 1.416v makes me think my E4600 has reached it's limit at 3.2 using 1.435 (even this may cause errors).

Cooler is a Xigmatek S1283 HDT with MX2 (not a heat issue - certainly not with the weather we're having!).

Vdroop? How can I control this on this board?

I can tell you from my own experience with the chips and from reading on this forum that most will hit 3.0Ghz without much trouble. You should aim for 3.2Ghz, is doable without to much vcore if you tweak it a bit. After 3.2Ghz these chips need a sudden increase in voltage, to much if you ask me.

I'd say your best bet is 3.2Ghz stable. Wouldn't go above 1.50v
