I've been visiting this site for weeks, and signed up yesterday. Awsome site! I'm thinking about building an OC system based on the D 930, but I noticed that there 2 types of 930. One states that its stepping is C1, and it comes with 1 X 4MB cache. The other states that the stepping is B1, also with 4MB cache, but comes with 2 X 2MB cache. What is the difference, and which is better. Also, can someone recommend a good board to use with this CPU? In the past, I have been very happy OCing Asus jumperless boards, but that was 6 or 7 years ago. Thanks in advance for the help.

I can inform you about the cache. There is only 2x2MB caches. It is a dual core CPU, and doesn't have shared cache (Unlike the Core 2 Duo), so 1 x 4MB would be a misinformation.<br />
<br />
I'm lost on the Intel area when it comes to motherboards, so no, sorry <img src="/images/smilies/redface.gif" border="0" alt="" title="Embarrassment" class="inlineimg" />

The difference is that the C1 supports EIST and the B1 does not. <br />
<br />
Personally I like EIST because while the processor is overclocked, the processor will change its full multi down to a x12, so if you have a 930, the multi will change from x15 to x12 which is a power saving feature. That is the only difference. In terms of L2 cache, both are equal, no exceptions whatsoever, 4MB L2 for both C1 and B1.<br />
<br />
Also, some C1s don't support ViiV but I find that feature useless because I see no point in using it. You can search ViiV on google. <br />
<br />
As for motherboards, the best is the P5B Deluxe right now, cost a pretty penny though, $230 at newegg.com. <br />
<br />
But I wouldn't recommend a Pentium D, I'd say get a Core 2 Duo CPU and the best choice is the E6600 for its price/performance/overclocking point at $313 but then there's the E6400 for $220 but it's a bit slower in performace due the L2 2MB cache, when the E6600 has 4MB of L2 cache. Is it worth it? I think so but everyone has its budget/priorities.<br />
<br />
So, this here is what I'd suggest: <br />
-P5B Deluxe with E6600 or E6400 and some DDR2 800 RAM, preferably G.Skill, Corsair or OCZ.

I forgot to mention that the Core 2 Duo CPUs are about 40% faster than Pentium Ds in come areas. Overclocked they're eve way faster......Look: <a href="http://xbitlabs.com/articles/cpu/display/core2duo-e6300_10.html" target="_blank">http://xbitlabs.com/articles/cpu/dis...-e6300_10.html</a><br />
<br />
BTW, I have a Pentium D 945 overclocked to 4.51ghz. It's fast but I rather use my C2D set-up.

although i own a d930, i'd agree with nasgul, go for C2D! but if u insist on the pentium D series, the p5wd2-e premium i'm using is quite good of a performer. =)
