How should I proceed on this E3 Venice 3000+ overclock on MSI Neo2 Platinum

[colossus]

So after spending time with my Venice 3000+ E3 (Stock Retail cooling) and MSI Neo2 Plat (Newegg Refurb) this is what I got:

1) HTT can go up to 335-340MHz when memory is at 100 8-4-4-3 and multiplier 5
2) CPU can go up to 9x288FSB = 2592MHz under Prime95 for about 5 min (no problems with Folding @ Home up to about 9x300
3) Here's the decision part - I have 4 sticks of 512MB Kingston HyperX 3200 that can do 5-2-3-2 up to about 210MHz and 4 sticks of 512MB Kingston HyperX 4000 that is supposed to do 250MHz at 8-4-4-3.

The system boots fine on 1.55V 9x288MHz with stock memory (I set the memory to 133MHz so it comes out to 0.666 x 288 which is like 185MHz). It runs Folding @ Home fine at this speed but fails Prime95 almost instantly. I'm testing Prime95 right now at 280MHz and it's stable for 20 minutes. CPU temps hitting about 50C on stock AMD HSF.


Question is how much of a performance hit am I going to be taking by running 2T (I need the 2GB of memory since Newsbin is going 24/7 and I often have 5-10 windows running). If it's not that much I'll just keep 4 of the HyperX sticks and sell the extra. If it is a big drop going to 2T - I'll be selling 8 sticks of HyperX

I don't game too often (maybe a game of CS and C&C Zero Hour every now and then - I'm still stuck on a Ti 4600). Is it better on most systems to have more bandwidth or lower latencies. Newsbin seems to really lag sometimes and it really eats up my memory - don't know if bandwidth or access time is better.

I was thinking of dropping the multiplier to 8, jumping the FSB to 315 (since 280MHz is stable under Prime95 at 20 minutes so [9x280]/8 = 315 and the HTT max was 335 or so in the first stage of testing, and then keeping the memory 133MHz so it effectively run 210MHz (a speed at which I could run CAS 2 5-3-2 using the 4 HyperX 3200s).

Any suggestions?

Here's some 1T and 2T comparisons: http://forums.anandtech.com/messageview...atid=28&threadid=1577496&enterthread=y

Also I'm running my HTT multiplier at 3X (since I'm at 282FSB right now). Is it safe on a Neo2 Plat to go to 4x282FSB (which passes the 1000 number). Most people in the xstremeoverclock tips site said go to 3X if you're past 290 FSB.

you could try it but kinda doubt it: 4x282 = 1128. just give it a shot and see if its stable.

Just to add some fun, here's a ton of mod/beta bioses for the Neo2.
Linkage.

There's a couple newer bioses out that will do a 150 & 183 divider also, which would likely help you out.

Yeah I saw that page a couple days ago (thanks for the reminder). Got disoriented by the table I guess since I thought the official 1.B Bios supported 183 Divider (that's why I flashed to official 1.B before all the testing).

I'm going to try v1.B Standard Edition by Sideeffect unless somebody thinks the v1.B4 variants are better.


I slowly dropped the CPU voltage down to the current 1.45V since I figured it would generate less heat and less stress (oddly the load temps jumped from the previous night's 50 to 53 tonight - but might have been because the room window was closed). It boots fine at 1.45V - should I lower it further or is it good to have the extra juice?

At 1.45V and 281FSB and memory running 360 (180x2) I was able to get Prime95 to run for 1 hour 10 minutes before it gave me a rounding error. Should I still go down on the FSB, go back up on the voltage, or look to put on better cooling? I'm sure if I had a Zalman XP90 on there it would go past 300FSB but it's not worth the $40 for me.

I just want to be sure it stable before I wipe the drive and get ready for my install so it becomes my main rig (don't want it hiccuping when I have all my data on there).

Any suggestions, anybody?

I'd wait until you have better cooling. You don't want to add too much v core when u are just under stock. Adding a little volts is fine but going to lets say 1.60 volts is a no no. You should take a look at the xp-90, very good heatsinkm, not as big as the xp-120.
