Have fun!

Shadow, get yourself registered and tommorrow or later tonight if im on i will give you admin creds.

On the phenom II what voltages should the N/B, Chipset, and HTT be at for heavy overclocking?

board is a m3n-ht Nforce 780a, i dont know the stock voltages for them.

I do believe I started the small PII 920 movement, and I still think that 90% of the people would be MORE than happy with that over the 940...of course that pretty black box does tend to raise an eyebrow!

That said I only have 1 single regret with buying my 920 and that is.....I'm a northbridge clock junkie and since it's an AM2+ processor the default high multi is 9x which will of course limit how high I can go. Anyway that hasn't stopped me from cracking 2.7Ghz on the northbridge already, but I don't run it at that speed daily just because.

My max clock on all 4 cores was a little over 3.8Ghz, and on just 2 cores I tested at 3.92Ghz. To get to the 'magic number' that we all seem to agree is the normal clock for the PII (3.5Ghz) it takes 1.440v to get 100% stress test stable.

Stock voltage of 1.344v yielded me 3.4Ghz but not stable.

Summary of the max clocks I've tested my Phenom II 920 at...

CPU 3.83Ghz (4 cores from bios)
NB 2.7Ghz
HTT 372Mhz (never found the limit, just gave up)
HT Link 2.5Ghz (again just gave up because there is no need for this 'extra' speed)


I'd say that's pretty sweet for a lock multiplier processor on air cooling with an ASUS M3A32-MVP (SB600) board and 4Gb of mixed ram (1150Mhz mixed with 800Mhz).

I love this processor and like I said the ONLY regret is that I don't have a higher northbridge multiplier or better yet an unlocked northbridge multiplier. The rest I don't even care about...

oh yea, with my awesomeness and tweaktastic ( <--- copyrighted word ) ability my 920 and full system uses only an insanely low 135W idling for 5 minutes and even when running multiple things like now I'm at................137W total system usage (had to lean over to check the meter)!

100% cpu load using Wprime the total system usage is still only 179W...beat THAT! (system listed in specs, add a billion USB devices to that too)

That would depend on what your system wants really...

Stock Northbridge voltage though is 1.175v and I've been up to 1.45v without any problems with heat using the stock northbridge cooler. I don't know the rest of the voltages though as, but maybe your bios will be able to tell you.
================================================== =============

I AM curious to see if my 'old' GeIL ram will go much over 1100Mhz stable though! I was bored one day so I decided to see if I could get any more headroom on my 800Mhz sticks and what do you know...

My old limit was under 1066Mhz and even that took some work! This time the voltage wasn't raised above 2.2v and they just cruised right along nicely. Funny after all this time my motherboard and ram are both really starting to warm up to me.

First the ram wouldn't go above 1066Mhz even on high voltage and high timings, then the motherboard wouldn't do any more than 272Mhz HTT if I begged and pleaded with it. Now the ram cruises above 1100Mhz with tight timings, and the motherboard doesn't blink an eye going to 372Mhz HTT. I swear my parts are alive and really don't want me to get my AM3 rig no matter what they have to do!

Man, as far as voltages im totally lost.

This DFI board got me 3.8 out of my 940 at 1.440v. The only voltage I touched was vcore. no other voltage was touched, all left at default. Man I wish I would have bought a DFI earlier.

Kei, I finally joined the Phenom II club

Glad to see yours is still going strong dude

Yey! More forums for me to sign up on *sigh*

I've lost track of most of them lol.

EDIT: I think I might have to get this bad boy once it's released: Foxconn AD7A-S 3.0

[ShadowFold]

I'm not much of a memory overclocker so, think this kit could do 1333, 6-6-6-20 1.8v
http://www.newegg.com/Product/Produc...82E16820148150

And I might grab this board
http://www.newegg.com/Product/Produc...82E16813131363

And I got a good deal on a used 720BE.

[Darknova]

I believe those sticks are the same ones Fits overclocked like mad, but can some one else verify that?

I was thinking about that board, but I'm just not sure...

[ShadowFold]

They are but I don't care for high memory clocks. I like lower timings I might wait for the 950 to come out, someone had their's at 4ghz with like 1.35v

That's why I've been looking at 1600Mhz DDR3 with 7 timings opposed to 9 timings, the extra speed (and architecture optimizations) should make up for the performance loss going from 1000 5-5-5-15 to 1600 7-7-7-18. Which was actually proved in benchmarks where DDR3 had around a 1-5% performance increase lol.

[ShadowFold]

What are some good 1600 sticks with cas7? Nothing over 90$ I hope..

Ah, there lies the problem. I've seen some great G.Skill RAM. HZs (black heatspreaders), but they're about £160 currently over here.

Corsair also do some pretty decent RAM, they're cheaper than G.Skill.

To be honest just look around, 1600Mhz is only attainable on AMD platforms by overclocking anyway.

[ShadowFold]

I just looked on newegg, the only good kit I can find is this
http://www.newegg.com/Product/Produc...82E16820146777
Kinda exspensive for ram..

[Darknova]

Quick scan of Newegg found me these:

http://www.newegg.com/Product/Produc...82E16820161294 - 8 timings, but Wintecs DDR2 kits are stellar, I'd take the chance tbh.

http://www.newegg.com/Product/Produc...82E16820227320 - 7 timings. OCZ Reapers

[ShadowFold]

I don't like OCZ and those sinks are too big. My CPU heatsink will most likely block them.

[Darknova]

Yeah, biggest problem with AMD boards, socket is far too close to the RAM slots.

http://www.newegg.com/Product/Produc...82E16820231167 - those were the sticks I was looking at, expensive I know.

[Darknova]

http://www.newegg.com/Product/Produc...82E16820148227
http://www.newegg.com/Product/Produc...82E16820148261

Crucials? 1333Mhz? 6 timings?

[ShadowFold]

I saw those crucial sticks, but they're 50$ more and I'm sure the 50$ sticks will do the same timings.

[Darknova]

Aye, it's entirely possible. Even Fits proved that buying cheaper RAM can net you the same results. In the end I don't think either of us has enough experience with DDR3 to say for certain, then again, no one can really say that each specific set will get you X speeds with X timings.

[Chicken Patty]

Shadow those sticks that you found, I believe have the D9JNL chips. They do indeed overclock like crazy and are a great pick for RAM, just get some aftermarket ENZO heat spreders like BINGE did on his i7 rig, those HS are sexy! Good choice on getting the M4A79-T DLX

that board looks good. I really wanted to try FOxonn but mine was DOA.

I believe it has something to do with ACC. Have you tried enabling ACC on all cores maybe????
