Testing DC and 2500 patriot vipers on ln2. I have issues getting cas 6 or trcd 10 to post. Always crashes at debug code 03, could it be IMC or am I doing something wrong with mems? I'm pretty sure these sticks should do cas 6 at 2750-2800+.

Also, my cpu cold bugs at around -148 degrees, but after around 6-6.2 I get memory access violation errors on the screen and if I bump multi up more the system will freeze but I can reset it via reset button fine, not a cold bug type crash. Am I doing something wrong or is the IMC just bad? Happens with memory on auto so 1333 speed and uncore was around 5.3-5.4 all the time when testing max frequency.

Also slow mode doesn't work. Ln2 mode seems to work fine since stock voltages are different and I can see jumbo V options.

Patriot sticks sucks again on ln2...no surprize.Lots of guys were complaining about this and also that they are slow when going gold.I would write other spd on those sticks and then try again ...

[Luumi]

Dunno alex, I have weird issues when going over 5.5 with HT and 6ghz with 1 or 2 cores, IMC or mem starts bugging, even if mem is at low speed. Things crash and I get pagefile bsods like 3B and 50. Do you have a link where guys say patriot PSCs are buggy on cold?

[bullant]

I have these patriot's I tested for stability a little while ago,they were quite good on ivy as well
2.15v -145 I think this was,not quite sure on temps now,they also ran cl6 but only 2666-2700,i haven't got them anymore as i gave them away

[Luumi]

Yeah weird, I don't get why it would be spd with cold temperatures. Sticks do 2770 8-12-8 twcl 6 on air with 1.94v. 2800 7-11-7 posts but trcd 10 and cas 6 will just give 03 debug code crash. Sometimes at 2800 cas 7 the RTLs were huge on the other stick like 45/10.

And bullant my sticks are 2500 viper II sector 5s.

[bullant]

yes I realize what your sticks are

Cas 6 2700+ is a tall order, you need the sticks and the imc to do it not just one or the other. I have never had luck with patriot on cold. I think it may be the PCB mine was 8117 black PCB, decent on air but best of 8 2400 Sectors did 2666 6-10-6 not a penny more. You can also try setting failure boot guard to 3 if you are having trouble training

Also, my cpu cold bugs at around -148 degrees, but after around 6-6.2 I get memory access violation errors on the screen and if I bump multi up more the system will freeze but I can reset it via reset button fine, not a cold bug type crash. Am I doing something wrong or is the IMC just bad? Happens with memory on auto so 1333 speed and uncore was around 5.3-5.4 all the time when testing max frequency.
DC and and pentiums do this for me as well and its very frustrating, I dont think there is a fix for it on any board. Uncore around 5.4 should be good, I cant do much more on the couple of ES's ive tried. When doing 5ghz and 4ghz benching, try to find what your IMC likes, not what your CB is. My CB is -125c but my IMC likes around -90c for 2820 6-10-6

Also slow mode doesn't work. Ln2 mode seems to work fine since stock voltages are different and I can see jumbo V options.
Slow mode works, just make sure thermal throttle is enabled in the bios in the CPU page. The way its implemented is it tells the system the CPU is over 100c so it kicks down to x8 so if thermal throttle is disabled it will not work.

Either way its a great start man keep pushing and I suggest the bullant style of benching. Slow and steady he always ends up getting what he wants in the end!

[bullant]

Yeah splave I think those Patriots Sectors 2400 weren't good bin hey,they quite bad on air too,great tips btw

@ luumi,just like splave has said huge cold temps not needed when just memory low clock benching,I quite often run my cpu on a SS @ -25 just to help the imc scale a little more,the main difference I see with cold on cpu and no cold is when pushing the memory with cpu air the rtls, iols will fall apart,were as with cold on the cpu it all keeps together

I would not care to much about cl6 at this stage,just see if you can get tRCD 10 to work,try @ 2600-2666 7-10-7-24 and see if it'll start posting,the 03 code can be your memory's are just not liking it.You can try different temps on your memory's too see if anything improves

Also I found sometimes when trying so many things, training and system become unstable,when this happens pull the battery out for couple minutes then try again

The other thing is what Dram volts are you trying to boot in at?

[marmott]

Good to know, thanks!

So I had under 2 liters of LN2 and just did real quick test of the memory's I bought not to long ago,the memory's not the strongest air memory's Ive tested but seem to like the cold and volts.With this test Ive also left the HS on the memory's,just clamped the KP Ney Pro on the top,so temps only about -130 Im guessing,just a boot in for now,it was passing few loops but with temps not full cold didn't want to push my luck.Im thinking these memory's may go to 2.3v on full cold,also have another kit of these that I only use for air and they are really good ,just different codes between the two kits,the Z97 OCF seems great with all the PSC kits I've tested
Pi,s 2300 cl8 kit, 28x multi and 2820 blk strap

[Luumi]

Ah so I just didnt how the trick for slow mode, ok. For 5ghz testing I just kept the cpu around -50, the really low cold bug was just a bug with me messing around. Now it cold bugs around -136 which is more normal temp and got better speeds aswell.
But the sticks wont post cas 6, not even at 2600. I always got 03 debug. The sticks are really good on air when doing 2770 8-12-8 twcl with 1.94v. I should try with another spd like Alex@Ro suggested, couldn't this be a good try?

[Splave]

Are you leaving twrrd_Dr at 5? Or 4 for c6 you need 5

[Luumi]

I had it about alwyas at 5.

[sergmann]

Hi guys, it's possible to get L0.12C Bios somewhere?
I can only find the 1.10 and 1.12

[Luumi]

I would like to know if that would even differ from official 1.10.

[Splave]

there are no trick bios' , just get the latest and be confident

[nXXo]

OMG i love your last pics Bullant crazy snow

[bullant]

OMG i love your last pics Bullant crazy snow

Thanks nXXo,that was a quick test and only used 2 liters of Ln2,maybe 1 hour session

[l0ud_sil3nc3]

Virgin 2800 c6 run no moar!

[bullant]

When I last ran 3D 01 I also had this little 200 point back up,will try different Ln2 bios as im still using the stock LN2 bios and just cant seem to get no more memory clocks,not sure if this may be because its a 3Gb card,hynix memory or bios :thumb:

[l0ud_sil3nc3]

Getting ready for IDF on Monday so decided to empty the LD 25 (about 15L) and what better way than to test PAE

Had this one sitting on the desk for a few weeks, go figure.



things got a bit wet so settled with this for low clock



2840 passed and then bsod while screening :p

[bullant]

Nice Loud, :thumb:


So no ln2 for a little while I did little air testing

Cpu on SS -25 and memory on air ,temps about 14c

2800Mhz stability 32M pass


Also did some testing on full bank memory's 4x2Gb PSC,CPU SS -25 and memory's on air about 20c on these runs.
If you take note on the above 28x memory you can see with this 4x2Gb im 1.5 sec slower,everything quite loose on the 4x2Gb for the moment,not to bad considering 4x2Gb is 2666Mhz
Memory's used in the 4x2Gb were Pis 2300 cl8,one good kit on air and the second kit is not very good on air at all,if I had used a better second kit im sure things would of gone even better

Will test all this on Ln2 when I have next refill,should see some nice numbers once cold



So still with the 4x2gb 2666,only now i start to tighten subs and few things,even tho not a pass it was only 391ms slower then 2800Mhz @ loop 18,with still plenty to tighten


So I tighten a little more and was running on par with the 2800Mhz,with still little more that can be tighten and only @ 2666Mhz


Was also getting some loops at 2700Mhz


Also doing 2736Mhz and just about all subs tight as they normally would be





all of the above were all rtls 40-41 and iols 4-4

here is little test i just did but had to shut down because moisture or something so wasn't able to test full stability

CPU on water and memory's on SS -20 full bank,would of been bit easier if cpu was on cold too

Should be quite nice once the cpu on cold and -160+ on the memorys

How ASRock didn't use a Intel I-218V NIC on this motherboard?

The Killer E2200 NIC uses more power consumption, and appears to have twice as much lag compared to the Intel I-218V NIC, as well as less upload / download transfer speeds.

Ill test 4x tonight mate,just had a refill today.


So because I had refill today that means more 32m posting from me around the forums,I like to spread the 32m memory love
