Possible GPU upgrade for Precision M4600

And where did you set that "60W at 60%"? I've browsed throught this whole thread, but failed to find any mention of, or link to, any specific version of Trixx.

 

VBE 7.0.0.7b is the tool to use to find those values. Not trixx, its a vBIOS alteration tool, then use ATI_winflash to install it. Of course, you do these things at your own risk.

Maybe your ambient temps are much higher than mine because those temps are really high, I would work on those temps before allowing more heat generation in your system.

EDIT: I just ran ValleyHD again. At 1000c/1500m I get 683 ExtremeHD preset

EDIT 2: At 1100c/1500m I get 726 ExtremeHD Preset

Which is also the limit of my card. I could I guess try 1.225v but I doubt it will carry me to 1200c so I havent bothered with it.

EDIT: Since the m4600 isnt my primary machine anymore I tried 1.225v for a 1150c/1500m but crashed. My max is 1100c/1500m on the m5100

 

Right then. I had a hunch that might've been the way, but i just wanted to double-check / make sure

I had used VBE before, to tweak the stock settings of the card, but "of course" with the 1.1V stock limitation.

 

Honestly I would just set 1.150v and 1000c/1500m and call it a day if your PSU can handle it.

 

Yeah, i don't have much reason to (want to) rev the nuts off this, but... Y'know, just for kicks, it'd be nice to see how far this can go

I'd be surprised if the power brick was the limitation - i'd much rather expect the VRM on the MXM board being the power-bottleneck.

But either way, i'm waiting to hear back on an offer i've made on eBay, for an E-port II plus, with a 240W brick. If i can have that at home, then i can use the 180W one the laptop came with as a "travel adapter" (ie. permanently in my laptop bag), and thus be free to update to the latest BIOS too.

 

1000c/1400m (or 1500m) is good for a 24/7 clock, well of course it depends on the silicon lottery.

Im starting to debate selling my m4600 again in favor of the y410p since my y510p died. I can SLI the machine and i have the ultrabay Desktop GPU adapter as well. For now I wont be doing anything with it though. School school school lol

 

Let's just say that "even just" having what's essentially a stock desktop 7770 (which this chip is), is quite an achievement in a 15" laptop (not even a 17" one)

 

You can also say is similar to the 850m which they more or less are.

 

Just a quick update:

I did some more tinkering, but for whatever reason, regardless of whether i set 1.175 or 1.2v in VBE, the thing wouldn't go over 1.15v (at least as reported in the latest version of TriXX). But that's not really important, i only hit a stability hiccup at 1075 / 1400.

The more interesting part is that, after (just for the hell of it) setting the "powertune" max to 75%, and just now, updating to the latest (17.11.2 as of yet) driver, i just cracked 701 in Unigine Valley in Extreme HD, at 1050 / 1450MHz, topping out around 87C - I'm ok with that

Might be worth keeping in mind i "only" have some Prolimatech PK-3 paste on there, not liquid metal or anything "sci-fi" like that. Or at least not yet, anyway...

Now, if only valuxin got that RX560 already... <biting nails> Figure another 2-3 weeks yet to go?

 

For daily overclock 1.150v is where you want to be anyways. Though that temp is way hot, your 16-17C hotter than I am, and Im not using liquid metal either. Just NTH1 (or NHT1?) thermal paste.

701 sounds right for 1050/1450. My 726 is made at 1100/1500 which all things considered is not leaps and bounds faster lol
