Replace CPU AMD TL-52 with TL-68?

I have Compaq v6066ea

CPU: AMD Turion64 X2 TL-52 90nm
Mobo: Quanta 30B7

Want to replace the CPU with another AMD TL
Is that possible?

Turion64 X2 TL-64 90nm (clockspeed faster)
2nd option
Turion64 X2 TL-68 65nm.


Could that give problem's 90nm to 65nm?

 

As long as you have the latest BIOS, it should support the 65nm cpu's since HP sold the V6000 series with 65nm TX2's. However the TL-68(2.4GHz) was only released recently and eventhough the BIOS might support the regular 65nm Turions, it might not support the TL 68 specifically. Try other 65nm TX2's like the TL-66(2.3Ghz), the TL-64(2.2GHz) should do fine as well and in any case the performance difference between all three processors are minimal.

 

so it should be no problem?
some dude @ amd forum tried TL-50 to TL-68 and had trouble due 90nm>65nm , at least he thinks cuz of that :

Thats an Acer and dont really know what the situation is with the acer BIOS. But the 65nm and 90nm Turion X2 are pin compatible as long as the BIOS supports them. AFAIK, HP used the same motherboard for the V60xx to V64xx series and they sold them intitially with 90nm followed by 65nm cpu's. Thats the reason why I mentioned that 65nm cpu's shouldnt be a problem as long as you have the lastest BIOS version.

Ofcourse, upgrading is still a risk but if you dont want to take that chance then the TL 64 should do fine.

 

then it should be no problem if HP uses the same mobo voor V6xx - V64xx series.
And should it be a performance boost? (TL-52 to TL-68)
That's the main reason ofcourse why i do that..

Already Upgraded RAM from 1gb to 4gb GEIL C5..
Next thing CPU and then HDD 16mb cache 7200rpm (current 5400rpm 8mb)

TL-68 on ebay is around 135 GBP..

 

I have a DV64xx model with a 65nm cpu. Since we use the same BIOS chip, an upgrade to a TL-64 should work at the least (as that is what was offered at the time).

 

and you have the same motherboard? Quanta 30B7 using 65nm? If thats so, i almost sure there would be no problem purchasing a TL-66 65nm, cuz that was introduced @ may 2007. TL-68 in dec 2007, my bios version F.3B 10/02.. Not upgrading to latest because of the fan, always on.

 

My board is 30B8, but the Compaq variants just use a "defeatured" version of the same board. I went with the F.3D BIOS, as it really keeps the temp down.

Anyway, if the TL-66 was available in May '07 then it should work. I bought my unit in June, but don't recall seeing it as an option at that time though.

Yep, AMD put it out in May but I don't think HP actually used it (TL-66) until the DV65xx/V65xx refresh (which used different BIOS & chipset boards).

 

so i should go for the TL-64 2.2 ghz 65nm? its around now for 85 GBP

 

It is the safer option, and still a considerable step up from the TL-52.

 

The TL-68's are all G2 core stepping chips, which the dv6000z series BIOS might not recognize. The DM at the end of the TMDTL68HAX5DM product code indicates the core stepping. You want a DC chip to be safe and those stop at TL-66. There are TL-64 and TL-66 DM's too so be careful. The G2 cores might work, or work with the exception of power management, there's no way to know until someone tries it. Definitely make sure you have the latest BIOS flashed in before swapping CPUs. If you have a vendor who's nice about product returns (ask first) then by all means give the TL-68 a shot if you're really curious and let us know if it works. Worst that happens is that the notebook does nothing on power up and you have to put your old CPU back.

 

Ah, good info Brian. I had not thought of the stepping.....

 

so if im right i have to pick CPU's with at the end DC? becauze the DM might not work, until i try? I dont have a product return shop, because i was planning to get it of Ebay.

Something like this?

EDIT: found the CPU-Z specs of TL68 compared to mine TL52:

 

btw according to LINK

All the TL cpu's are ending with DC except, TL-62 and TL-68.

and what about the HT-link speed? mine 400mhz, and TL68(probably TL-66 to) is 800mhz

 

Yes, the TMDTL66HAX5DC is the safest bet for you.

 

Did you take that screen shot while running under battery power? if so, then it is just HP messing around with the BIOS setting the HT multiplier at 2x instead of 4x in order to save power/reduce heat. The TL-52 like all Turions has 800MHz(1600MT/s) bus.

 

Yes but i now noticed that.
Batt+ AC power = HT 400mhz
AC power alone =HT 800mhz

I asked the dude on Ebay if he could refund if cpu is not compatible with my laptop and he agrees. (TL-68 one)

So i was wondering how the HT Technology works, because TL-68 works on HT 1600Mhz. Does it depend on your motherboard or is it controlled by the CPU ?

 

All Turion X2's are capable of 1600MHz(its not actually 1600MHz but rather 1600MT/s and is misquoted quite often). The HT bus runs independent of the cpu frequency and runs off of the 200MHz base clock speed and is amplified using a multiplier from 1x(200MHz) to 4x(800MHz). This is set in the BIOS and is changed the same way for all Turions. The 1600MHz speed is often used because the HT links are capable of dual data rate transfers, they are capable of transferring twice the amount of data on a single clock cycle. Thus a 800MHz HT bus can be rated at 1600MT/s or as being capable of the same transfer rates as a bus capable of single data transfers running at 1600MHz.

Bascially, dont pay much attention to the HT links, they are the same 800MHz for all current AMD mobile cpu's and its speed can be altered by the BIOS on the fly depending what the OEM chooses.

 

where i can buy AMD TL68 ? i want upgrade for my dv6636nr with TL58. Should i upgrade?

 

The only place i can get is Ebay,,

 

I do not know if you are still following this thread but a great source for fair priced AMD and Intel laptop cpus can on eBay, more specifically at a store called genius heart which can be found at http://stores.ebay.com/genius-hearts_W0QQssPageNameZstrkQ3amefsQ3amesstQQtZkm. I have purchased an Intel X9000 among other CPUs from them in the past for great prices and I, like you, am looking for a TL-66 or TL-64. They currently have models of both in stock, I just checked, at prices mostly under $150.00.

The other deals you find on AMD laptop cpus on EBay typically come out of China, and not only are shipping costs high but you have very little recourse; a shipment from China is NOT a shipment from Hong Kong.

Genius hearts is located in the US, I do not recall where, but shipping is not a problem cost wise and If they do not have a cpu in stock they will try to get it for you. I have them marked in my favorite sellers list and always check them first when I need a CPU. I am a lawyer who builds computers in his spare time as a hobby with my sons and I am in no way affilated with or work for genius hearts. So if you cannot get a good deal or they do not treat you right, which would be out of character, I have no responisibilty other then representing that I have gotten some good deals from them.

If this reached you too late I would still be interested if you could let us know how your upgrade went and any problems you may have faced? I am looking to update a TL-60 to a TL-66 and really want to know if it would be worth the money and and pitfalls you may have run into.

If this info does not help you hopefully it will help someone else.
