How is everyone else setting the memory timings?

I thought this would be like my Asus board where you can leave what you don't know how to configure at auto and change the timings you do know. But it's either Auto for everything or full on manual mode for everything.

I notice when i change the memory speed from 1066 -> 1333 -> 1600 that there are two columns of values next to each timing that also change. These columns, "SPD" and "Auto", are next to the column where you actually change the values:



I was thinking I could use these values to manually set the timings, but (unlike the screenshot above) some are drastically different comparing SPD with Auto... I know the SPD values are programmed into the memory, but where is it getting the Auto values from?

[daseto]

show us some screens of when it is in auto and SPD, then ya might get some better help. Gotta see what you are looking at to try and figure out the best way to answer your question

[naokaji]

I'm hoping that you have better luck and that naokaji's experience was just a rare bad one.

The UD5P I got to replace it while waiting for the rma is working fine*

* minus usual issues of newly launched hw (bios setting ram timings far away from spd timings, oc auto recovery not working reliable and such minor stuff), but no serious problems.

is it too early to know if this from a good batch?

Yup, too early, time to push it to the limit

[Hemi345]

I'm at work now. But see the screenshot above and imagine, for example, that "Write recovery time" is 12T for Auto while 24T for SPD. Would the value for SPD be the one you'd choose to manually set it?

[daseto]

Idealy the SPD should be the rated timings for that RAM, but at times they arent all that right, and some mobos do not read them correctly. If you can find some white papers for your RAM, or someone else that has the same sticks and compare values, you should be able to kinda get an idea of what the RAM should be set at. One thing you might do, is try to find info about a DFI mobo and their mem settings. I know its weird, but DFI has a loyal following and some guys that are good at explaining what does what. OCForums had a guide for the s754 DFI Lanparty UT NF3 250GB and explained every single memory timing. DFI usually has a million options for memory in their bios and im sure there are guides out there that talk about DDR2 and even DDR3 timings from the intel camp. While you have a diff mobo, memory timings are pretty much standard, just some manufacturers decide to show you alot of the list, or some of it, and i believe DFI gives it all to you. In the very least, you would likely find some info as to what each timing does, and if you can find a comparison between a ddr2 775 board and a ddr3 775 board i think you might be able to see what is right with the timings for your setup that you are running.

Okay, I posted over on Corsairs forum last night and in the mean time screwed around with the timings. I basically took the average of Auto and SPD on the timings I didn't know how to configure (scientific, I Know!). So if one said 30T and the other 25T, I manually set it to 27T. Set the voltage to 1.8V memory to 1600mhz and it booted up and was stable for 3 passes of memory stress in Orthos. Man is this system snappy! And I haven't even started overclocking yet.


Someone from Corsair replied to me this morning. This is what they recommend:

DDR3 Timing
CAS# Latency = 9
RAS to CAS R/W Delay = 9
Row Precharge Time = 9
Minimum RAS Active Time = 24
1T/2T Command Timing = 2T
TwTr = 6T
Trfc0 for DIMM1 = 110ns
Trfc0 for DIMM2 = 110ns
Trfc0 for DIMM3 = 110ns
Trfc0 for DIMM4 = 110ns
Write Recovery Time = 12T
Precharge Time = 3T
Row Cycle Time = 40T
RAS to RAS Delay = 7 - 8
DQS Training Control = Skip DQS
CKE Power Down Mode = Disabled
CKE Power Down Control = Per Channel
Memclock tri-stating = Disabled
Bank Swizzle Mode = Disabled

Just built a similar config with some GSKILL 1333 as I got a great deal on it, do these X3 720 BE's really run this cool? Mine with CNQ enabled is at 18C with a 940BE Heatsink (waiting for my water cooling which I should be getting tomorrow). If so I cant imagine what I can OC this thing to.

[DPGX]

Also wasnt able to run Overdrive :-( It says it cant detect my CPU, any suggestions? 3.8ghz so far on stock volts, not going to play with voltage until my waterblocks on.

[Hemi345]

Either the temp sensors are off, or they really do run this cool. Last night it was idling with CnQ at 21C. Played that FEAR demo and left HWMonitor running and it never got above 37C. Ambient is 20C. That's with the OEM HSF that has no heatpipes on it.

I was able to sorta get an old version of Overdrive working but I don't think it supports the Phenom II X3s very well, I couldn't change the multi on the 1st core, but i could sort on the 2 and 3... if i set it to 16, it would drop back to 15.5 when I clicked Apply.

Thanks for your updates the past 2 days I ended up doing the same board and chip, I think CoreTemp may be off, mines only listing 2 cores, CPU-Z see's 3 cores and Windows does too. This seems like the budget chip to buy right now, I absolutely love it. I cannot wait to throw water cooling in this case and push it more. My only disappointment was that OEM heatsink lol. Im use to as of late seeing the heatpipe coolers ship with BE chips from AMD, I had two that arent being used though and threw that on it until Saturday.

I couldnt be happier right now I just wish AOD 3.0 was out.

[Hemi345]

See if you have the latest version of CoreTemp. Mine shows the three cores and reports the same temps that HWmonitor does but I'm starting to think they're not reading the correct sensor. If I fire up Gigabyte's Easy Tune or whatever it's called, it says the CPU temp is the same as Sensor #2 in HWmonitor... which also is much closer to what the BIOS reports for CPU temp. Idling around 35C.

Last night Overdrive wouldn't work at all on my system...it would lock up the machine while the msg indicated Overdrive was reading the information from my PC. I really only want to use it to play with the multipliers in the OS.

I was able to boot and run a few games at 3.4ghz no problem at stock voltage (17x200).

turn off any other hwmonitor before you run aod

[DPGX]

Are you running the 64-bit version of Core Temp? I grabbed it last night off the coretemp site and its showing 2 cores idk why.

CPU-Z indiciates 3 cores as does task manager.

[DPGX]

Just found this over at AMDzone may explain temps a bit:

Check out the AM3 listing for thermal monitor.

[BrowncoatGR]

Someone (I think Informal) posted earlier that the latest AOD doesn't work with Gigabyte boards and that you need to use the previous version

[N00B]

Just a tip i think you can use your old opteron Artic cooling cooler on the new phenom

[Hemi345]

Thanks. I polished the base on the Arctic Cooler64 this weekend, I'm going to slap that on tonite. Should help alot with load temps compared to the stock cooler.

I'm going by what "TMPIN1" says for temp in HWMonitor as it matches up with what Gigabyte's EasyTune6 and the BIOS reports what the cpu temp is.

I got the Overdrive 2.1.4 (I think that's the version, one back from the latest) to work fine. I ran the stability test and watched the cpu temp go from mid 30s up to about 48C. Then bumped the multi to 15x for 3.0ghz (no change to voltage or fsb) and the temp rose past 55C till I stopped it and decided I needed better cooling

[Hemi345]

No, i was using probably 32bit of Core Temp... I wanna say version 1.55? It showed three cores, but the same extremely low temps that HWmonitor is reporting as the "core" temps. TMPIN1 seems much more realistic.

[DPGX]

Yep :-) thanks man I just went back to Win7 32bit to play around a little more and core temp lists all 3 cores. Also that GB Util isnt half bad either.

Hello. New guy here.

I have this motherboard and an X3 720 BE processor. It's assembled on my desk but I haven't powered it up yet.

Memory is Mushkin DDR 1600. It's actually a three-channel kit purchased with an i7 920 in mind and then I changed to the AMD processor. It should run at CAS 7 at 1333 from what I've read, but we shall see.

My cooler is a Scythe Mugen II. This is a huge cooler but it fits with only one minor clearance issue - the memory. The 120mm fan sits right on top of the Mushkin memory, which is a little taller than most, but shorter than some. Something a tad shorter would be a more comfortable fit.

Question: Why are the white slots recommended? The User's Manual says if just one pair of DIMMs are used they should go in the blue slots. This has been found through experimentation to not be the case?

This is a nice looking motherboard. I like the layout and it has a quality feel.

[Hemi345]

Evidently, memory supposedly just works more reliably in the white slots. A few people on here as well as the Corsair forums recommended the white slots. I haven't had time to experiment to see why. But when I mounted up my AC Freezer64 last night and there was no way that cooler was fitting in the orientation I wanted in if I had left the memory in the blue slots... so maybe the white slots are recommended for that reason as well?

I haven't had a chance to tighten the timings further than 7-7-7-20-1T on my Corsair memory at 1333mhz either. Wanted to try that out but getting the cooler mounted and checking temps and such took up most of my limited time last night.

[Hemi345]

7-6-6-18-1T @ 1.7V are the tightest timings I could get memtest-stable (3 complete passes). 6-6-6-20-2T had errors halfway thru the first pass.

[N00B]

Can you unlock the 4 cores?

[Hemi345]

No. I believe it's only doable on AM2+ boards with the "right" bios.

Someone from Corsair replied to me this morning. This is what they recommend:

1. Enable DQS training, the way Memclk works with the DDR3 controllers now is that even the slightest of changes requires DQS/Memory training routines. If you are using a windows based program to change HT ref clocks, do it one or two steps at a time in order to let the system reset Memclk values correctly. You will get a lot further with the memory clocks in this fashion. The best way is to simply go as far as you can in the BIOS and use a Windows utility to get that last extra increase in clock speeds.

2. I do not know if this is in the F2 BIOS (using F3B), but keep an eye on TFAW, very important setting and the Phenom IIs like running it a little looser than the i7s. 30 is recommended at 1600, some memory will take 24 at 1600, some will need 36. If you can run 24, it will offer the best performance.
