x61s L7500 overclock by installing dell 1705 wifi card

[axur-delmeria]

Can this DW 1506 network card hack only work on x61/x61s machines? What about the x60/x60s/x60t?

The x60 family has a different base FSB (166MHz) compared to the X61 (200MHz). I'm not even sure if the 945GM chipset has the 266MHz FSB setting; then there's the big question of whether it will be stable at that clock speed.

Thank you for your reply, even though it's over my head! My interpretaion is, don't try it. Too bad, as the DW-1506 does not heat the palmrest nearly as much as my x60 machines that are using the AR5B95 network cards.

I took the DW-1506 network card out this evening. It was causing the laptop to run hot, always.

Can this DW 1506 network card hack only work on x61/x61s machines? What about the x60/x60s/x60t? I received a DW 1506 card, yesterday. A few days ago I put the l7500 motherboard back into the x61s, I had x60 Librebooted motherboard in it for years.After removing the heatsink and cleaning the fan, new thermal paste and thermal tape I've used it daily since, in preperation for the 1506. I tried several different sets of ram memory, but finally tried some Kingston 2GB PC2-6400s 666 800MHz sticks and wow, this really does work! Since I haven't used Windows since July 2011 I can't run any benchmarks, but I know that it's running the 2.4GHz or thereabouts. I actually installed Win 7 to a drive recently, no updates, but that is for Ivyprep only, x230.

I've tried this (DW1705) in my X61s L7500 too with 2x4GB Hynix DDR2 800MHz sticks and it works BUT the system locks up because 1 of the 2 RAM modules doesn't like running at 883MHz (lol). Need to try SPD tool to downclock back to something more stable (fingers crossed). The other module seems fine with the OC, but after 10 mins of use the system locks up, so again stability is a problem without downclocking

Did you need to modify your SPD on the Kingston RAM sticks at all?

Do post if you try on the X60... although I think it's one of those quirks of the X61 chipset that won't be easily replicated on another chipset

enable intel speedstep, which will let the system dynamically manage clockspeed - so you're not always running at 100% CPU

also try undervolting and re-pasting the CPU with Thermal Grizzly Kryonaut or Gelid GC Extreme (pretty much the best TIM)

[Libre_ME]

How do you enable Intel Speedstep?

[Libre_ME]

I found it, in CPU menu. It was enabled already, but mode for scheme for AC was set to "automatic", I changed it to "battery optomized". Same for scheme for battery, I changed from "automatic" to "battery optomized." I'll put the DW-1506 back in and test it.

The display was also set to "high", I put it to "normal." That did the trick. It's very well behaved now! Thanks a lot for letting me know this trick!

no prob that's what I'm here for

enjoy!

I meant toanswer your questions but got sidetracked/forgot to. I didn't modify anything. I just kept switching modules until the x61s would boot and then I'd test.

This evening I put the DW-1506 network card in a Librebooted x200s, 1.6Ghz. It definitely improved it's performance significantly and without the overheating issue, as well. I just ordered 3x more DW-1506 network cards. If I find anything else out I'll post here.

Just curious, why are you opting for the DW1506 instead of the DW1705?

[Libre_ME]

I can't remember why, now. Maybe the link to the 2012 German Thinkpad forum influenced, but I can no longer remember. I've had the DW-1506 work in both x-models that I've tried it in. Am I missing something by not trying the DW-1705?

Also, I'm looking at Kingston 4GB memory modules with pc2 6400s 800Mhz specification. The one that I'm interested in is 1.8v, not 1.5v or 1.35v. My 2x Kingston 2GB memory modules do not have the voltage written on them so I'll have to research to see what voltage they actually are. I do know that after installing the DW-1506 network card that all kinds of memory sticks would no longer let the x61s boot, whereas they did with the AR5B95 network card.

I think the reason your RAM didn't work with the DW1506 is that they're forced to run out of spec - hence why modifying the spd (down clocking) is necessary. Unfortunately it seems that most RAM doesn't allow spd modification. Some user reports suggest that the Kingston RAM is the only one that is easy to modify or might not require modifications. I'm on the hunt for some now

And not sure on the differences between the DW1506 and DW1705. I'll look into it. What is the ar5b95 card you mentioned? Does it offer a shortcut to pinmod too?

Edit: it looks like ar9565 is the DW1705 viewtopic.php?t=127571
Atheros AR9565 (aka AW1705) and AR5B125 (aka AW1506)

So what is the ar5b95

[iamdmc]

How did you find unlocked RAM chips?

Any chance this forum member has more? I'd like to pm

The ar5b95 is the recommended card by the Libreboot project. I don't know what's exactly so special about it save for the fact that it runs opensouce firmware. I have 8 Thinkpads and 7 of them were using this card, but boy do they get the wristpad hot! As of yesterday only 3x of these machines are using the ar5b95 network card, now 4x of them are using the DW-1506. The DW-1506 network cards might also be using opensource firmware, as well, because I read that any Atheros network card from some time in 2009 and forward that all have opensource, auditable, firmware.
I put a DW-1506 network card in an x230 yesterday and it really seems to be running much better, faster, than before. I know that there are benchmark tools for Linux nowadays, but I'm not a very technical guy, just an enthusiastic Thinkpad/Linux user, but it would be nice to able to show some numbers/evidence to go with my performance increase claims.

I put DW-1506 network card in x60s, with l7400 cpu, using the 2x Kingston 2GB modules and there does not seem to be any increase in performance in that machine.

Different chipset so pinmod won't work

I just got a mint X61 T7300 4GB RAM
HDD is swapped by a 256GB Samsung 860 Evo
Yesterday I did the Middleton BIOS upgrade
Made it definitely snappier
Now I want the upgrade / speedboost using the DW1506
I already ordered a DW1506
But my biggest concern is the memory
What brand / type will get me the processor speed boost ?
I'm looking for 2 x 4 GB sticks but not easy to find and if pretty pricey
Or should I just go with 2 x 2 GB
All advice is welcome !
