Athlon II x4 630 OC. Any suggestions?

System specs:
MB: XFX 750a am2+
CPU: Athlon II x4 630 at 3.25Ghz 1.43V under load
Ram:o CZ 800DDR2 5-4-4-15 at 2.1v (currently at 5-5-5-15-24@2.0v)
GC:XFX 9800GT
HSF:Athlon x2 6000+ Stock HSF (4 copper pipes 3250rmp)

OC:
FSB:250
HT:x4 = 1000
NB:x8 = 2000
NBmultiplier:x13 = 3.25Ghz
Ram:833Mhz
Load Temp: 59C
Idle Temp:27-29C

Will I gain anything (or is it even wise) to try to raise my HT and or NB?
Would I gain much if I get my ram to 5-4-4-15?

Any other suggestion would be great.

You Could Try To Raise Your NB But Id Reccomend LOWERING The HT

(I Set My HT To x4 And Raised My NB To 240 To Get To 2.8GHz OC On My Stock 2.3GHz AMD A64 X2 4400+)

Lowering Your Timings May Also Help Since In Most Cases CPUs With On-Die Memory Controllers Prefer The Lowest Possible Latencies. I Actually Get Better Performance On My Machine Running My DDR2-800 (Rated 5-5-5-15) @ 667 4-4-4-12 (Raising The Voltage To 2.1v To Achive It) Than Running It At The Stock DDR2-800 Speeds

I Would Even Go So Far As To Say Go Find Some CAS 4-4-4-12 Or Lower Rated DDR2-667

You'll Hafta Experament A Bit To Find Out The Best Combination As I Did

My Next Machine (No Doubt DDR3) Will Run DDR3 - 1333 CAS 6-6-6-24

Would lowering my HT to 750 bottleneck my system or is that plenty fast enough? (i noticed your HT should be at 960 (4x240))

HT is the one place i still do not grasp competely(the how much you need and why). I know AM3 boards usually have like 2k and am2+ 800ish? but no idea why.

Update:
I did some more research on HT, AM2+ boards (or at least mine) suport HT3 so i set my multiplier to x8 so my HT is now at 2000 and running well.

I also tried to bump NB multiplier to 13.5 or 3.375Ghz

Doing stibility test. I think Ill work on ram after I get CPU where I want it. Will update again after 6hour prime test (or sooner if fail).

Update: Failed prime95 after 35 minutes. Might would be stable with a voltage bump from 1.44v average load, to 1.46v average load, but not sure I want to up the voltage that much. Expecially with temps at 59 max load already.

Tried putting my ram at 1000mhz (didnt expect it would pass) it didnt.

Running cpu @ 3.25Ghz and ram at 833 5-4-4-15-24 and checking stibility.

Any suggestions would still be wonderful.

That's pretty much where I am stuck. except mine is 50C on load (must be the Canadian air). I tried decreasing the multiplier and getting it further but I couldn't. I'm using stock voltage. without a voltage increase you're probably stuck at that level.
