Ch5 under the microscope

Thanks, I will take a look at this, although I don't have that kit. Did you try just shifting tWR and nothing else?

The 4GB DIMMs I have here don't have this problem and neither do John's 2GB DIMMs.

Throw them back in and give tWR a shift in a bit.

Do you get the failures at the DOCP preset without shifting the FSB?

No it's fine, I have headroom to 1023 after that it's a no go, trcd at 11 probably cut them some slack.

tbh this set and gtx 3's in general I would term as a tuners model.

They have never been as forgiving as my Flares however when tuned right can surpass the flares in primary timings ( not subs however )

Well then there's no real problem Chew - because the DOCP profile is for DDR3-2000. The rest comes down to manual tuning and it's not worth us setting tWR to 10 over DDR3-2000 just for one set of modules when everything else works ok.

Well save for the issue that the ram is rated for 2400 as is the DOCP at those timings not 2000....there should in theory be a comfortable amount of headroom which there isn't presently.

We aren't talking about some budget set of ram in this case.

Is that RAM rated at DDR3-2400 on AMD or Intel?

We are looking at what most people will use and are not going to invalidate the board's general functionality for one set of modules - when you can run them at DDR3-2000 and make changes as required to clock higher. Most modules need a tWR of 12 over DDR3-2000 so that's what gets precedence I'm afraid.

Of course intel.

We can't create a custom profile that recognizes these dimms by SPD and adjusts accordingly?

We can't start doing vendor/module specific profiles, as it would soon become cumbersome. It will be easier just to help users who want the extra bandwidth out of modules like these - there won't be many that have them and those that do are generally tweakers.

Allrighty then, moving on to other ram.

Ok so this is what you guys wanted to see right?

Board prep first as always.

I should note the board performed exceptionally well from beginning to end, no more cold issues as with previous boards. No more stolen clock syndrome after only 1 hour of benching, it performed almost flawless albeit there are a few small things I will bring to ASUS's attention to see if we can get them straightened out

[Leeghoofd]

Seems to a lot of headroom left Brian go go LN2...

One other tidbit I forgot to mention which i discoverd last night which will effect the extreme crowd.

For those lucky few that managed to scoop one of these AMD specific pot's up from Vince before he discontinued them be forwarned, You will either have to cut the PWM sink to make clearance or look for another board.

[SF3D]

Good thread with a lot of details.

About the CPU power connectors. 4-pin is just for IMC and 8-pin is for the rest.
First I was also wondering, what they have been thinking, but knowing the purpose made it look better.

Keep the scores coming! There is not that much amd guys around.

How much space you have to work with with your ln2cooling pot?

My 90mm pot was very tight on the CHIVx and I tend to like a "little" insulation

Good stuff on the 4-way action!

It's roomy enough. I didn't take exact measurements but yah you can still wrap it once it's installed.

First, I came when I saw this.

Second, Thanks for the words of advice with the Venom pot. You have any pictures of the cut heatsink? How much frost build up around the back component wall even with heavy insulation?

I'd rather not cut mine but it is an option, in my case I just used a different pot.

There is a decent amount of frost but diff insulating methods can overcome it. Just need to adjust methods to the application.

I've always been able to bench with my PWM soaked in water due to my methods, not gonna fly for the eraser guys but imo eraser has it's uses and it has it's misuses.

Just because there is a lack of benchers/competition in no way means you still shouldn't try to push the limits

There will be 1 less AMD guy around in the near future, It's time for me to step down and take a break once again like I did shortly after working with ATI on manta and grouper.

[PatRaceTin]

wow this is good thread

Ok so after my quick ln2 run on this board i did run into a small issue that needed to be worked out, basically this serves dual purposes.

Air/water guys on ln2 with locked cpu's and ln2 benchers.

Had an issue with higher htt, I needed higher htt as an ln2 bencher do to some recent changes AMD made to agesa code which limits NB multis.

Here's what you get with 300 htt for options.

At 250 htt 4000NB is just not going to cut it but 300 htt will max out the majority of cpu's.



Apparently there are some possible auto rule issues that are being worked on. For the time being just set the primary timings normally found in cpu-z and touch no other timings, leave them auto, even if you set them to what auto is setting them manually you will find a no post situation. You may have to hit reset a couple times to get a sucessful boot.





While runnig the above I happened to notice something else rather odd, in cpu tweaker MRL is very very high for channel A only.

Do not use cpu tweaker to change this, it will apply but it's not actually applying. Use AOD instead as a workaround for now.

As you can see from these 2 shots it impacts latency slightly when at an optimal setting.

[FlanK3r]

omg, it is mega POT . How with preparing RAM slots? Its good "only" electro-insulating tape? Or its better this plastic "modeline"?

[chew*]

While I was fooling around with HTT I decided to test a real locked chip, unfortunately the IMC is not to great on this one at very high htt however if you run more conseravtive settings 300+ is easy.

300 ram 1600 6-7-6




I dug an old set of 8 gig out that I reviewed, nothing stellar timing wise..........just running them at rated and 333 htt was easy.

Quick question -
Is that your square one or a rectangular Venom? A pot like my venom rev 5 should be fine by my calculations, considering the pot is considerably slimmer (like 1/2 inch) on the PWM/memory sides. On my pot, the edge of the mounting holes for AM3 are almost equal to the inner wall of the reservoir. It will be tight to wrap, however it should fit.
