Let's bring the discussion back into focus :D
Were we able to run SK8V @ 260 with Corsair RE? No....
SO let's take what we've got and run with it! I want to put this thing under ice and push for big clocks even if I'm limited at 240mHz (HTT, whatever)
What are we all complaining about? Locks? Well, no.... because better than half the owners here have functioning locks. The Vdimm is our current complaint. The key here is going to be the "perfect storm", when someone with a 6800U/x800XT/Pro gets an a8v/fx53/BH5 and combines it with super cooling. I will be obliged to do this in a couple days (minus the Vid Card)....
So I'd say the KEY right now is for someone to get some 3700EB and run it up to 250-260 @ 2.5-2-2........

:thumbsup:Quote:
Bigtoe,
Thoughts on my idea of OCZ 3700EB running up to 260ish on the A8V?
C
Thanks bigtoe!
So who's gonna flash first and report back with Vdimm options up to 3.2V???????????????
:D
C
I flashed... vdimm is still maxed at 2.8.
What are the changes?
did you use e-z flash and just add .rom to the filename?Quote:

p.s. amazing! 10,000 views in 12 days.....
of course, 3784 of them are mine, lol
I used ASUSUpdate. It recognizes the bios as 1005.021 in bios and CPU-Z.
Hey Bigtoe! How about a BIOS for the K8NS Pro? I'm dying for CPU multis and perhaps a little extra VDIMM and VCORE.Quote:
Please???:worship:worship:worship:

3700EB...dunno m8...boards clock ram so its hard to say, all depends on how the board overclocks ram.
nycxandy
Its supposed to allow higher overclocking..how much so you guys will have to find out.
StormPC
I get what i can...and post to keep you guys happy...If a bios comes available i will post it up.
To all
I haven't looked at editing these A8V bios files yet so there may be some tweaks.
If you have a spare bios chip or saviour post here so i can organise a beta test.
Im NOT promising any gains but i will have a look.
Just wondered if you had heard anything.
Thanks bigtoe!:toast:
Oh ok, because I don't see any additional or different options listed within bios.
It's hard to keep up with all the developments. LOL. I downloaded and installed SetFSB and Clockgen for A8V today. I then go to work and find out Bigtoe has another BIOS available. I'll flash when I get home tonight. Thanks Bigtoe.Quote:

Im doing my best...we have asked for more Vdimm so it should show up if the board allows it ;)
No it locks as soon as I plug in the mod.Quote:

Yeah, I understand that... but more importantly, can you boot at 2.8V and TURN UP the Vdimm to 3.3??
C
is it possible we've been concentrating on the WRONG chip???? less than an inch away is ANOTHER LM324............grab pin 6 there maybe?????
C
p.s. in fact after looking at a sk8v modded....I really think the first mod was incorrect!
Thanks!!Quote:
Well the read is correct when you adjust the mod in real time, so I think we have the right chip unless there is an alternative spot. But it does adjust the vdim.Quote:

ive not had a glitch or a reboot at stock speeds and my locks havnt been off since i got the option in bios. So i dont know what there talking about or my luck is still holding strong(i should buy a x800pro i'd prolly get a nice clocker if this luck keeps up)Quote:

Still, if it will get through a 3DMark run, that's all you need, right?;)
Im all flashed to the .021 beta but its WAY to hot to try to be overclocking right now as it is one hot mother. ive got my case side off. 4 80mm fans and unrestricted airflow and im still gett'n 42c cpu 30c board temps:explode:
maybe, so who's gonna try 1st. I've laready smelled burning silicon once this week on this board. lolQuote:

AWESOME!!!!!!!!!!!!!!!!
This also means that the Japanese OC GODS are about to set some WR's with 939/FX/A8V
Not terribly difficult mods, too....
GET YOUR IRONS FIRED UP!!!!!

here they are:
TAMS Vdimm looks the same as ours though...http://219.113.251.125/c-board/file/A8V_Vddr-mod_2.jpg
version2 Vdimmhttp://219.113.251.125/c-board/file/A8V_Vddr-mod_1.jpg
I'll try these charlie and the second vdimm. Not sure what would be different between the one I tried and tams. What size vr for the vcore
That first one is the one that doesn't work. Has anyone done that hard sodder successfully? Confused now.
What's the highest RAM frequency you guys can run on this board at 2:1?
I top out at 228MHz @ auto V.
-
I e-mailed Mushkin about my problem and this was their response.
"Well I was looking at numerous forums and it looks like your chipset is topping out ( this is across different motherboards and manufacturers the only similarity being the K8T800 chipset) at 231 at the highest, some are going only 224 while still others are topping out at a meek 213. It does not seem to be a limitation on the memory, but on the board. Mind you I did not see any stats on the overclocking of that board, though as I said earlier I have a feeling that it is a chipset limitation."
Is this true?
so is he saying that a 5k vr set to 2.15 or the original is 2.15 and set to 5k for the mod? I wonder if this mod really works. That's a really tight sodder point.
I think you're OK....you're at 228 with only 2.6V (auto)??? that's good! Just wait til you shove 3.2V through it!!!Quote:

That second Vddr is a b*tch. you have to unsolder a sm chip and stand it on it's ear to solder a wire to it.... youch! Similar to HiPro5's IC7 mod.
I think the parantheses are showing the original value of the SM part.
My GUESS would be to start at 2.15K Ohm resistance and increase in small increments and watch Vddr.....????
May be easier with a fixed resistor!
C
No thanks. Jeeezz! I like your find another chip method better. ;)
Well, this memory is rated at 250 @ 2.8V max. I've tried using 2.8V with 229 and it still wouldn't budge.Quote:

BTW, I've tried each stick individually and they both perform the same, topping out at 228. So both sticks are the same.
-
And to the Mushkin statement above... It seems like Anandtech was able to run the Samsung PC4000's up to 245.
"We were able to reach overclocks as high as DDR490 at 2.5-3-3-10 timings with Samsung PC4000 on the Asus A8V Deluxe. However, we were not able to reach the specified DDR500 speed on the dual-channel Socket 939 Asus A8V Deluxe."
http://www.anandtech.com/memory/show...ml?i=2082&p=14
More or less same here. I'm not convinced these locks are doing anything and frustration is setting in fast.
Oh, ok..... I should have looked more carefully at your sig.... I thought you had Mushkin L2 BH-5.... That seems more like an Intel "lovin'" ram.... let us know how it goes!Quote:

Charlie, that Mush 2 is exactly what I have in there right now. No ceiling difference whatsoever between that and my XL's. That's why I doubt the lock. Also I just tried the #1 vdim mod again and I set it for the exact same voltage as what my 2.8 bios equals (2.87 overvolts) and it boots but then freezes going into windows, so the mod itself seems to be "F"ing with the board somehow, not so much the voltage. I'm stumped on this one.Quote:

Guess it's time for some experimentation on the Vddr mod....
Now I'm FAR from an electrical genius (god knows) but what if we remove the surface mount resistor in version2, and just replace it with a fixed resistor, let's say 5K ohms..... if the Vddr power comes from 3.3v rail, it can't damage ram, just push it to 3.25v or so....
Here's what I think about v2 mod. It's like Hipro's IC7 Vddr mod, you replace a resistor with fixed resistor and also solder in a VR. It gives a much more stable Vddr mod....without fixed resistor, it used to bounce 3.20v-3.28v, 3.18v, 3.26v, etc..... after adding the extra fixed resistor, it was like 3.26v-3.28v....
So if someone replaces the 2.15Kohm with a fixed 5Kohm, it should max out the 3.3v rail....possibly unstable....but adding a resistor would give the stability.
Or do it like this: with a 2kohm fixed AND the 5K VR (just like a IC7 mod)
My interpretation is that with the R422 inserted upright that they did that so that adding the 5K would put the resistors in series versus parallel -- parallel being standard practice when adding a VR to an IC or to an onboard fixed resistor.
To me, it would be better to remove R442, solder a 2.15 fixed resistor to one leg of our VR and soldering the other leg of hte fixed to the solder pad. Then solder the free leg of the 5K to the other solder pad.
Also, with the method of adding the 5K in series, you would have to set it to zero ohms before hand as it appears that we are increasing the resistance in this circuit in order to affect the Vdimm.
charlie is right, the values in parens are the onboard stock values.
Are there any 8 pinned SC1211 ICs in the area around the Vcore Vreg?
The SC2643 has the standard FB pin (#7), but also tied to Vcore is pin #6. The Vcore Vreg has a "Differential Pair for Remote Sense" when related to Vcore. Pin #7 being Vcore+ and #6 being Vcore-. I would still say modding #7 is that way to go and doesnt vary from basic practice.
charlie, can you check the mod location shown in the Vcore pic to see if there is connectivity to pin #7 on the Vreg? I am pretty much positive there will be and they chose the mod location mainly because soldering to the uber tiny pins of SC2643 would be suicide.
You could be right...since I havent worked on this board and the mods are pretty new.Quote:

But, if the idea is to raise the resistance to raise the Vdimm...then going by your pic would lower the resistance.
Either way, try it your way and see what happens...it cant hurt anything.

hell Fire,
Yeah, you got that right! There's a SC1211 right next to the Vcore mod area...
tell us more :D
I changed my MSpaint image above reflecting your recommendations, look correct?

Okay....update.
The 1005.21 is definitely more stable. It seems to have eliminated the random "flakiness" I was getting when using the PCI/AGP locks.
260HTT is a breeze now...no doubt at all the locks work. 3D2001SE has no issues looping at that speed.
I'm off to get the Clock Gen and SetFSB apps and try some serious OCing.
BTW, any links for those apps? Can someone lend a hand asap?
Also, I'm still working on the volt mod. First one didn't work. I'm gonna try one of the other methods pictured here...
mdzcpa,
for the sake of completeness, can you list your mobo number, for example mine is a OJ3276
and is that 260 1:1??? (or 2:1 whatever)
I think I posted the serial number earlier in the thread, but :
45MGOJ2879
The 260HTT is not 2:1 (1:1). My Corsair XL won't get there with any kind of decent timings and my stock 2.8v. The best she can do at 2.0-2-2-5 @ 2.8v is 225. Above that and until 250 it needs 2.5-3-2-5. I haven't tried for more as I am not interested in looser timings than that.
I NEED VDIMM!!!
Excellent! With your gear, when are you gonna' lay down some 33-34K 3DMark01 action :DQuote:

Just to orient it to the pic on post #6, the fixed resistor leg would be soldered to the top pad and the VR leg to the bottom pad.
I was just asking about the SC1211 as there is usually a cluster of those connected to the SC2643 IC.
charlie, can you do a connectivity test from R167 to pin #7 of SC2643?
Anyone attempted the Vddr yet?
Aircool no Mods KHX3200.

yes, sir....both sides of r167 connect to leg 7 sc2643Quote:

Now about the Vdimm, it's such a PITA, I've been looking at it, and it's just like the early 1st Vdimm IC7 mod but worse, thos epads are Soooo tiny....heat em up too much and they just fall apart.... then mobo = garbage....
I wish I had one of these in front of me atm. ;)
charlie...do me a connectivity between pin #6 on LM324 and R422 please sir.
yes it's connected, too... but the atx side of 422is "strong" wjereas the other side of 422 has a "weaker" connection (the resistor)Quote:

That would make sense as it has the most direct connection to the FB pin on LM324.
Out of morbid curiousity, is there a connection between R456 or C715 as well?
none or faint connection
Ok..I couldnt tell in the pic if a trace was connecting those 2 resistors.
Seems like the AGP/PCI locks are working with SetFSB.
it's possible I ve got a gigabyte Nf3 939 MB today to compare.
I've already broken 33K without much work at all. I'll post screenies tonight (I'm at work now). I'm thinking 33,5 should be feasible at rock stable speeds.Quote:

great thanks. I'd rather have ocz 3700EB at 3-2-3-5 than XL at 2.5-3-2-5 at the same speed but the ocz's damn near non existant.
ive gone up as high as 275HTT, 280HTT doesnt work but my temps are way to high. 40c/28c idle with 26.5~27c room temps:( and thats stock. Hopefully i'll get a reply about rads from soulsend at mhq and jp will ship my v5 today.
Just received the replacement board since the last one freezes everytime I enabled the AGP/PCI lock. The new one's serial no. is 46MGH1XXXX.
Will update the BIOS with 1005.021 and see if this one is trouble free with the lock. Wish me luck guys!!
228 at 2-3-2-5, but this FX53 is throwing random freezes at any speed on this board. I guess the FX53 issues remain even with 021 bios.Quote:

Anyone with boards with working locks do a test for me.
Disable your agp/pci locks and and set to 1000HT check sisoft sandra to see if you have the reported 2x1000(2000 double data rate) that you should have. Then reset your locks without change'n ldt and see if you still have the reported 2x1000HT. Mine drops to 2x800 with the locks enabled.

Do you have 2T command rate set to disable or auto etc?
What is the best your XL's will so at 2-3-2-5? 1-1 and 2-1
Any word on the details of the vcore mod?
This may just be coincidence, but I've noticed that people who have serial numbers beginning with "45MG0J" seem to be having fewer problems.
Did you guys with the FX53's get retail or oem processors? Any difference? I rma'd back my retail FX53 but ordered an oem to replace it since the retail parts were out of stock. My oem replacement arrives today, but I'm considering refusing shipment and getting another retail part, which just got back in stock. Any reason to do that? I obviously won't use the retail hsf anyway.
I have an OEM and I haven't had any trouble. So far, without mods, on an LS I've ran spi at 2947 and 2001se at 2959
I always thought OEM processors will be the LATEST week runs...

also has anyone tested the locks/1000HT issue i noticed? if its not just me maby we can have bigtoe look into it.
That's fine about uploading SetFSB. That will save me a lot of trouble. :) As for the 1000HT issue, are you talking about the Sandra readings? I've noticed it measures my maximum bus bandwidth at 884MB/s.Quote:

yea. turn off the locks and check sisoft sandra again.
k setfsb link is
http://www.mechwarrior.tv/pictures/A...bU15a1_A8V.zip
With the lock off, I lose about 300MB/s in Sandra. The bus bandwidth still reads 884MB/s.
That's kind of odd.Quote:

very.
I tested it this morning when i 100mb/s behind another FM user at the same settings(must find that 100mb/s!!:mad: )
But at x5/1000HT set. 200x11 2:1 2-2-2-5-7-16 with the locks on it reported at 2x800. But i didnt loose any bandwidth. With the locks off at the same settings in bios it reported at 2x1000.
I dont see how the locks would effect bandwidth:confused:
I'll try and test again later. I have to run out and do some chores.
By the way, I ordered some 3700EB. I want to see if I can get better FSB.
512meg sticks? and if so from where?:slobber:
No, 2X256MB. But I heard OCZ is ramping up production again on EB, so the 512's should be available again in the near future.
ah. im holding out for 512 meg sticks so they better hurry up.
Let us know how they do. Im really look'n forward to see'n some some 250x10 1:1 with at least 2.5-3-2-5-7-16 timing 3dmark01se lobby runs. 345+fps lobby low and 160fps+lobby high at only 2.5ghz with DS sticks would be a sight to see if it goes that high. 233x11 1:1 2-3-2-5-7-16 gets 329 low 150 high with SS sticks
Well, despite the lack of mods and using a POS 9800np. I'd have to say this combo is pretty fast. 25.1k at 460/320 just about matches the score I got on a p4c at 3.98 and an 9800xt at 540/435. Just getting board waiting to find an X800XT in stock

My replacement FX53 just arrived and FX53/A8V stability is dramatically improved. I don't know if that's due to the 1005.021 bios or the processor change. I'm still in the process of determining the maximum stable processor frequency (currently air cooled). Ram is 1gb Corsair XMS3500C2.
I hear the BIOS is much better. Could be the processor, or that it's just seated better.:)Quote:

first strange buggy thing is that when I have mem set to 2:1 (DDr400) cpu-z says I'm at 170Hz??

On HTT and memory or just memory?Quote:

You're vmods working ok?
Seems to have a bit of OC headroom though.....1.6v ambient 27C.
Anyone know why 2:1 divider is giving me like 5:3 or something???
YOu know I remember some kind of similar thing on the SK8N.... but can't remember the solution ;)
Well, I can't seem to figure the dividers out.... I have set MEMCLK to LIMIT and then 2:1 (DDR400)
Still don't get 2:1 in reality :(
Hopefully some of you A8V veterans have some answers for me...
BTW, was anyone asking about functioning locks :D
...unfortunately my BH-5 is only good to 235ish on 2.8V, playing earlier I actually got it up to 302HTT with 8X multi... but real instable!
OH! and does anyone else's A8V turn itself on when you flip the PSU switch?
Doing great charlie, I'm not sure why you're getting that. 2:1 works for me the way it should.
suggestions?
or here?
Your bios looks different than mine charlie. Mine has an option to select 2t at the bottom of the memory configuration. Everything else is the same and that's how I selected 2:1
oh, I HAVE the 2T command, you just have to scroll to see it :D

Gotcha. Maybe try reflashing the bios. I've noticed on my other asus boards that using alt-f2 or the ez-flash sometimes screwed things up.
Charlie, you might try lowering TRAS. I found that setting it at 11 didn't help. High TRAS seems to be more of an Athlon XP thing.
This brings up a question I've been intending to ask, what's the optimum Tras for this board, 2-2-2-?. Wesley Fink in his recent article at Anandtech said he found best performance at Tras=10. Guess I need to run some tests.Quote:

On another note, the lock on my A8V seems to work great. The board serial number ends with J2872, which falls in the range that's supposed to work ok. I'm currently in the process of seeing how high I can push my 1gb of xms3500c2 at 2.8v. Update: 219mhz is max at Trcd=2. I have to change to 3 to go higher. A bit more Vdimm would be nice, I always ran it at 2.9-3.0V on my P4C800E.
You might try clearing the BIOS to failsafe defaults before you start tweaking just to make sure you don't have a wrong value somewhere. I've had some funky settings coming with supposedly new motherboards. It's always good to start with failsafe values for max stability, then change only the settings you need to.
No luck......
I reflashed the BIOS and reset CMOS.... even first time it fired up (default) the memory was running at 160 (5:4) Strange. Eben tried different sticks, no luck.

That is weird Master Yoda, have you tried selecting 5/3 or other dividers and see what happens.
Edit: another possiblity is that your copy of the bios is corrupt in some way. Maybe download it again or try the .20 bios
think it may be possible that the mobo "see's" my sticks as PC2700 (KHX3000) and won't run 1:1???????????????????
