weird, board passes orthos blend at 480fsb yet if i was to play tf2 for a while, quit the match then suddenly start up a new server it will crash to desktop and come up with an error about memory unable to be read. imo thats an mch error, happens at 450fsb too just not as often. only certain fix is to lower fsb to 425. i guess the mch cant handle the stress of the high temps caused by gaming combined with having to load a tf2 map.

Did you try and raise the MCH? Maybe run memtest to see if your ram is stable.

[lundrog]

Just ran HDTACH on my raid 5 configuration. A mixed match of sata drives I had laying around.

I set this up as my OS drive.

Thoughts?

[RAMMAN]

happened at 425 fsb too, but this time got an actual bluescreen and reboot. this problem only happens when loading a tf2 map after tf2 has already been running for a while. even at 480fsb it passes all known stability tests and plays all other games for hours, even other source engine games. has there been a tf2 update recently which causes memory errors in certain situations?

BAM, man i love my UD3P

just took 8th spot and still trying....

Some screenies would be nice. The last time I tried a raid 5 configuration the write speeds were abysmal, but that was a long while ago. How are they for you?

Nice work Systemviper! A few more MHz and you'll be up there!

RAMMAN you got the L version that will not do the same as the UD3P version...at least thats on ya signature

[andressergio]

G.Skill PIs FTW!

Failing that you could get some Tridents which will do over 1200 as well.

The ripjaws are another option, but with rather naff 6-6-6-18 timings.

I think most manufacturer's have quit the DDR2 PC9600 game, which leaves us with very little choice.

agree the Gskiils PIs rock

[In-Fluence]

Yes they do! What kind of speeds were you able to get them stable at? Did you buy from memoryc?

I can't seem to get over 1250 without getting errors in MT5 - GTLs & Skews make little difference along with voltages so although I'm still getting some nice DDR2 speeds in comparison to my old 4GB kits, I hoped for something between 1250-1290 for benching purposes (like I had for my reapers). I guess an even bigger amount of NB volts might be needed, but I don't want to damage anything.

For now I'm testing with the 2.50A divider at 1233MHz (493x9) which I think will make a nice 24/7 setting without pushing voltages on anything and will allow me to run semi-passive for a nearly silent system - just what I need for my music

2:50 strap is bugged after a certain mem speed and will give you errors. Skews will play a big role here.

For benching a good 2x1Gb will always be better then 2x2Gb mate no matter how good the 4gb kit is.

Hey Viper

Nice max valid I missed you around here.

+1 for that Jor

[RAMMAN]

as i mentioned before even 485x7 passes 1024k orthos, 480x7 passes 1 and a half hours orthos blend and 490x7 locks up 2 minutes into 1024k orthos. all of my best 3dmark benching runs on stock cooling were recently done at 475x7.5 no problem. and i have been running crysis and all the other orange box games for hours at 480x7 no problem.im starting to think this issue has something to do with one of tf2,s recent updates.

yes i am using the ud3lr so im definitaly surprised its actually bench stable at 485fsb 1.3 vtt 1.24 mch 2.2 vdimm

Hey Viper

Nice max valid I missed you around here.

Hi bro, yea great to hear from you, i have bee nplaying with as many chips and i can get my hands on to get more hwbot points. That UD3P is just killer but once i getover 550 it gets very wak. I think i might be able to push it more with the Q9550 but i am taking a break and gonna slap in a E6500K, that should be fun....
Everywhere i look you are right there, so it should be a fun few months, i look forward to talking more

[The Viper]

agree the Gskiils PIs rock

R we all talking about the same G.Skill PIs, I know the older gray ones were really good, but theyve been replaced by the newer version.

Also has anyone experienced problems with PCIE slot or RAM slots not working properly on the UD3R or UD3P. I just got RMAs back (RAM and GTX280) and unless they sent me broken RAM and a broken GTX280 soemthings up with my board.

[clo007]

I went thru 4 EP45-UD3Rs. I was having issues running dual channel. There seems to be a weird grounding issue causing it, unless with mine it was that. i got a new case and it works fine now.

[In-Fluence]

opps, here, broken link.

Looks like a nice read speed on HDTach there. Is the Sandra test for disk write speeds? If so, that's very nice too! How many drives are you using and what type/size/brand?
If this offers the speed benefits of RAID0 and the safety or RAID5, I might just jump onto RAID5 again myself!

Thanks for the tip Jor3lbr, what kind of 'buggy' do you mean, just p95 instability? What speeds do they start to play up at?

The only reason I ask is because I'm reasonably stable at 489x9/1233 PL8 settings but it fails around the 640k fft test.

[MarcusFoX]

Hows the stabiliy and Vdroop a regulation with these board been since the first Bios guys... have they got any better since F1 or do they still have a fair amount of vdroop I ask because im thinking for switching away from my
M2F and going with a EP45-UD3P or R.

Also would there be anything else id need to know from all your experiances.

LMK

[In-Fluence]

After coming from the MIIF I would say the LLC does stabilise vcore just as well on the UD3P. The UD3P does undervolt by about 0.3v (for me) while the vcore on both the MIIF's I had were spot on. Memory is also undervolted by about 0.2v on the UD3P.

Thanks for the reply.... I figure there was some vdroop to a certain degree. I got a q9550 sent to me in canada im trying to push the extra mile.. my M2F will post only up to 485 then after that I have to mess with GTL's and Shew and still 500fsb is very unstable for a prime run. thinking about getting one of these to too up my overclock.

[RAMMAN]

i have a theory, this problem that only happens while or soon after loading tf2 maps has only started recently, only change i can think of during that time is 50ps mch skew. for comparison 490fsb with 50ps mch skew is more stable than 468fsb 0ps mch skew. of course neither of those 2 settings are orthos stable. perhaps 50ps mch skew is a double edged sword, gets me an extra 25fsb but causes problems loading large maps? or should i be looking elsewhere for a fix to my tf2 problem? most common symptom is a crash to desktop with memory cannot be read error or sometimes hl2.exe needed to close.

But if its not orthos stable isnt it then, by definition, liable to cause errors at any time? i.e unstable and imho not reliably capable of performing daily functions such as loading tf2 maps? I would just stick with highest stable settings so i could enjoy my pc error free.

[RAMMAN]

490fsb @ 50ps and 468fsb @0ps are just examples to show just how much mch skew affects stability, i never actually use those settings. as i mentioned before 480fsb passed 1 and a half hours orthos blend before i stopped it, it has also run crysis and all the other orange box games for hours non-stop no problem at 480fsb.

[arctic-k20]

Hey guys - trying to gain that last little bit of stability on my setup....the settings i have now can intel burn test, and ran prime blend for almost 10hrs before i got an error. So i am close but not 100% yet. Any suggestions would be really helpful!!
