Getting a 1055t to 4GHz

post #1 of 28
Thread Starter 
Hi forum,

I recently picked up a 1055t from our very own Klue22 in a deal, and I'm looking to get it to 4Ghz. Let me tell you...It is a pain!

Assuming a 14x286 setup, it won't boot at anything less than 1.5v (CPU LLC is enabled). At 1.55v (which is about 1.52v in CPU-Z) I can run OCCt for about 3 minutes before a crash.

My RAM is rated for 1800Mhz CL9 at 1.7-1.9v, but I've typically run it at 1600Mhz CL6 or 7 given that AMD prefers tighter timings and lower frequency.

I've been shooting for 2.6 or 2.7Ghz CPU/NB, with anything from 1.4-1.5v (it doesn't seem to like anything less than 1.3v--BSODs before even starting OCCT).

Any thoughts? My load temps aren't great, but their under 55c. Are there some funky voltages I should tweak (e.g. CPU VDDA, HT voltage, straight NB voltage, etc)?

I can tell that this chip is going to be very difficult to get to 4ghz, but alas, that is my goal and I intend to see it through! Any help is appreciated!

I'm actually trying to do the same thing. Highest I can manage stable is 3.5ghz, trying to push further. Not doing well though.

Edit: Also, I think you mean 14x286, 386 would be 5.2ghz.

I refer you to this thread. I'm going to tinker. I want my 4.0.

Yup, I meant 286. Let me know how the tinkering goes. I am going to do some tinkering of my own until I get more feedback.

raise cpu/nb volts to 1.35

tighten your timings on your ram chips/ lower your ram speeds

I've got the NB at 2700Mhz @ 1.35v right now. 1600 CL6 is pretty tight, don't you think?

I can boot at anything vcore over 1.5v. I can run OCCT for at least a few minutes at 1.55v or 1.6v (a little high, I know).

I think I just need to work on getting my cpu temp down, unless anyone else has any bright ideas/things I might be missing...

I capped at 3.9ghz. For some reason, regardless of multi/voltages (I was pushing a LOT of volts through my system) I couldn't raise my FSB above 280. RAM is at 1488mhz 9/9/9/20 (stock 1333/9/9/9/21). I'm debating on going down to 1180 or whatever the alternative is and trying to tighten up my timings but my RAM is performing better than it has according to a RAM benchmark.

This chip is frustrating the crap out of me... On my 955, I could do 4.0Ghz (20x200) @1.45v, 2600Mhz NB @1.3v, and 1600CL6-8-6 @1.8v.

I heard these Thubans were supposed to have good IMCs, and that most 1055ts could reach 4Ghz, which I why I made the upgrade.

So far, the most stable I have achieved was 10mins of OCCT with the following settings:
CPU: 4.05 (13.5x 300) @ 1.55v
NB: 2700 @1.35v
RAM: 1200Mhz CL6 @1.8v

My RAM is rated for 1800Mhz @1.7-1.9v, and doesn't like low frequencies very much. It's also very picky about timings. e.g. I can boot 1600 6-8-6 but not 1600 7-7-7. Go figure

Any thoughts? That 10minute run of OCCt was the best I got, so maybe we should start from there.

I need a 1055t expert...(Xd, I'm looking at you!)

why are you running cas 9 at cas 6? run it at cas 9. specs are specs. cas 9 not made to run at cas 6. regardless of clock speed. if you want cas 6 buy cas 6. you bought cas 9 set cas 9. maybe once you're stable with your memory at default then you can try and tighten timing. but its super obvious that its your memory timings at this point.

post cpu-z tabs, like this, for further assistance. its a lot of text to read and arrange - everyone has an easier time just getting the info from cpu-z (print screen, mspaint, ctrl+v, crop, save, manage attachments, done) should take u 1 minute to get the screenie up, and save anyone reading your thread at least 5.

I'll clock up to 4ghz if you guys wanna see my set and I can post cpu-z tabs. I wont stability test it in this case though. its not set up to handle all that extra heat.
